@fcwilt said in What are the G Code commands that affect stepper feedrate?:

The H1 lets my endstops stop my move. This is true with G90 and G91. When I put H0 or nothing at all the motor tries to run passed the endstop.

H1 is to be used when homing as it will set the axis position to axis min/max (depending on the location of the end stop sensor) when the end stop sensor is activated.
You don't use it just to try and solve a problem with moving past the axis min/max.
If normal moves are not limited to the axis min/max perhaps you have a M564 somewhere disabling the min/max limit. You could also have a problem with your homing code or your motor steps/mm settings.

I removed my M564 command and tried using my home files instead, but no luck. My steps/mm settings are fine, at least I think so since my axes movement distances

I dont like G91 at all it is messy for sending displacements of a specific distance haha!

What does that mean?
I meant the opposite, sorry! I always have to calculate the motors position before sending a command with G90. I am interested in moving the motors for particular distances, so G91 is much easier for me.

At that point, either it is due to the newer firmware, or my duet is broken!

Yesterday I tried with the slowest speed possible, I was sending 25mm movements with a feedrate of 300 (i.e. G1 X25 Y25 Z25 U25 F300) and was also slowed by a similar factor. I had around 8 seconds instead of 5 per move when moving more than one motor.
That makes me think that it clearly is a software setting somewhere that slows it down? Or it just cant compute more than one motor? Since it is slowed down even more when the command I sent it should already be going slower than the speed it used to go to when I was asking 1500 feedrate, I doubt it can be hardware related.

I am starting to lose hope on what else I can do to solve this. I already read the whole G code page in search for useful settings.

@droftarts said in What are the G Code commands that affect stepper feedrate?:

I find the positions that the printer stopped at very odd. Did you do some moves before running the script? I suppose it doesn't really matter, as you were using relative moves, but it is outside the bounds set by M208, though you have overridden it with M564.

If I inderstand correctly, the positions written here are the code from pause.g?

@bearer said in What are the G Code commands that affect stepper feedrate?:

you pressed pause and the duet ran pause.g which by default contain some retraction g-code...

@droftarts said in What are the G Code commands that affect stepper feedrate?:

In your move script, the H1 is unnecessary, as you're not homing (I think). If you run in absolute positioning (G90), change this to G1 X0 Y0 Z0 U0 F1500

The H1 lets my endstops stop my move. This is true with G90 and G91. When I put H0 or nothing at all the motor tries to run passed the endstop.

This is the new config.g. The problem isnt solved, but I dont like G91 at all it is messy for sending displacements of a specific distance haha!

@droftarts said in What are the G Code commands that affect stepper feedrate?:

@jcsb1994 your config.g is missing a U value in M201 (max acceleration), so likely using the default and slowing all axes in a coordinated move as a result. Send M201 on its own to check setting, and do the same for each of the other motor settings. Testing each axis individually and seeing if one is slow would be the way the sensible way to test this.

For the sake of completeness: the default for a movement axis (i.e. not an extruder axis) is 500mm/s².

Also it could be simply tested. In the current setup moving all axes except U should work in the expected amount of time while also moving U axis will slow it down.

Thank you for your keen replies. I have checked with M201, my M201 U value was at default 500.00 as expected. I set it to 1100.00 in my config.g and checked again with M201 at bootup and it was effectively set to 1100.
But it doesnt seem to be the problem here. It didnt change anything, I double checked all my individual axes and they move normally by themselves. the problem is when I start moving more than one, even X and Y simultaneously start to slow down.
I am wondering if a setting is making the MCU compute too many things for more than 1 motor?
I didnt try it yet, but maybe 1100 as a max acceleration is too low, too? But i wouldnt see why, since the motors are ok when by themselves. Maybe the board has a design flaw or something broken? (how would I be able to check that?)

@bearer I am familiar with C and C++
learning bash doesnt seem too long.

I would need the project to be cross platform. Is bash only usable with linux?

Basically, I have a script that generates G code made out of while loops for the duet. I just want the duet to receive those commands automatically. Ideally the easiest method would be to send the commands directly to the duet via USB through a terminal opened by my script. This is what I did before I start using while loops, which do not seem to be usable with direct USB commands, and it worked great. The problem was that I need to send repetitive commands for long periods of time, and I would eventually fill the buffer because there is no way to stay in sync with where the motors are in their operations, the script has to estimate when to send the commands.
That being said, a while loop is much more efficient and the motors can indefinitely loop. But I am forced to generate a file.g since I cannot simply send this via a USB terminal, unfortunately. I am not sure I understand the solution you offered. The duet was connected to a Pi's USB (which is linux so bash works) and then the Pi was connected to your computer?

Since the user will be on a computer (i am on windows right now) I need the person to be able to run the script and ideally the file.g that this script generates can be automatically brought to the duet

finally got around to trying this on a Duet2Wifi w/ RRF 3.1.1 that wasn't attached to a Raspberry Pi over the SPI interface which for now breaks some of the SD card operations..

Wait, that wasn't or that was attached to a Pi?

What language is this file in? i am not familiar with this syntax. I am really interestted in trying this out

@bearer I have tested with 3 motors of the same model (the one at 1.8deg step) and no luck, the moves still take 1.5s each instead of 1 (1.1 maybe with accel/decel). It doesnt seem like having different motor models change something.

@bearer Ha ok thanks I understand.. I didn't see it this way I thought it meant where it paused on the running program.

And if a motor current is limited in such a way that it limits its max speed below the required feedrate, will the other motors slow down even if their current max setup will let them reach the required feedrate?

undefined · 28 Jul 2020, 21:18

@Phaedrux Ok, so I changed my max current values for 1400mA on the 2 bigger motors. But it didn't change anything.

I also had a weird message.

I started by uploading this script with the upload and start button

echo 12345

while true
	G1 X25 Y25 Z25 U25 F1500
	G1 H1 X-25 Y-25 Z-25 U-25 F1500
	M122

M0 H1

And made sure the movements were taking significantly more time than a second each.

Then I pressed on pause, and this message appeared:

The Printing paused message seems wrong. there isn't even a line ith these values! is the code being changed when uploaded to the Duet3d??

undefined · 28 Jul 2020, 20:18

@Phaedrux
I tried increasing the Vin to around 24V but the movements are still slowed. my 24V power supply was pushed to its current limits however (4.8A consumption, and its rated 5A).

Here is what I get with M122. Everything looks fine even at 23.5V but the problem persists.

@bearer no voltage drop! During movement:

It is not a clone, so I am really puzzled right now...

undefined · 28 Jul 2020, 17:32

@Phaedrux I just found out what made the feedrate slow down. It isnt the firmware update, it is the fact that I added motors to my board! It seems like operating 4 motors compared to only 1 drains too much current for the duet3d wifi. Is there a solution to this. As of now (I just tested) with this command:

while true
	G1 U25 F1500
	G1 H1 U-25 F1500
M0 H1

I get around 1 sec per move (plus wastes from accel/decel)

But when I use this command:

while true
	G1 X25 Y25 Z25 U25 F1500
	G1 H1 X-25 Y-25 Z-25 U-25 F1500
M0 H1

Then I get up to 1.7s per move, as I explained before. It seems linear however, I get a little slower at 2 and 3 motors (around 1.5s per move).

Is there a current setting to correct this or it is a physical limit to the Duet3D wifi? I am using

M906 X700.00 Y700.00 Z700.00 U700.00 E500.00           ; Set motor currents (mA)

for my motor currents, and I my 4 motors are actually

2 X - 17hd48002h‑22b
2 X - 17hm15-0904s

all of which are nema17. Is there a setting for max board current? I am worried about increasing the max current for my individual motors, the 17hm15 can't/shouldnt go a lot higher.

Am I right thinking it is a current issue?
Thanks!

Hi,
I am trying to implement a while loop meta command in one of my projects. It works fine when placing it into a g file that is uploaded and run as a print file.

;test.g
;echoes 12345 and executes a successful while loop
echo 12345

while true
	G1 X25 F1500
	G1 H1 X-25 F1500

M0 H1

But I want to see if it is possible to send a while loop via direct usb serial commands (i.e. through sending G code on a terminal). When sending the same string to the terminal (and making sure the indentation is still present) the Duet3D discards the while operation and does the moving only once.

"motors: while true\n
    G1 H0 X25.417066 F528.000676\n
    G1 H1 X-25.417066 F528.000676\n"

Is it possible or the while can onlu be used inside files?
thanks!

Hi, I am looking for a way to upload files automatically to my duet3D and use them without having to use the web interface (basically I want a command prompt script to send commands to my duet3d, but directly sending the g code through usb caused a bunch of missed commands)

I have found the M559 command, but I cannot make it work. I tried typing the whole file path:

M559 P"C:\Users\...\Desktop\test.g"

But I get an Error: Can't open file for writing. I can't find a way to use this command..

There also is this post where @lolorc mentions "in the mean time, i'll continue to upload my files through usb serial"
https://forum.duet3d.com/topic/8513/duetwifiserver-1-22-released
I really tried looking at how to upload files through USB but I cannot find any documentation online.

Then, I plan on using M23 and M24 to run the uploaded file directly from my command line application. Is this feasible? If so, would it be better/easier to use M559 (sent through USB anyway) or upload through USB (if lolorc doesnt refer to the same thing)?

The key thing here is that I dont want to have to click anything, once the file is generated, it can be uploaded automatically and run on the duet.

Thanks for your help!

@Phaedrux I tried looking at his recent posts, but there are so many!! I didnt have any luck finding something on feedrate bad conversion.

My program used to work however. I wonder if this can be caused by upgrading to reprap version 3 (I used to be on RRF2 when it worked).

undefined · 27 Jul 2020, 23:41

@Phaedrux Yeah! (not in this example however). But even when correcting Feedrate for accel/decel losses (which are pretty small) I have more than 60% increase in time taken (feedrate is basically 2/3 of what is should be on paper)

undefined · 27 Jul 2020, 21:51

Hi,
I am trying to send commands that last for a specific period of time, given their feedrate and amount o move, this should be more or less predictable.

This command:

G1 H1 X-25.000000 Y-25.000000 Z-25.000000 U-25.000000 F1500.000000

is supposed to move my motors for about 1 second, but it takes around 1.7s, although the distance of 25mm is respected.

I have setup my config to convert steps into axis movement correctly since distances are right. But I do not know what can be wrong to have 70% time increase on my expected feedrate!

here are the commands I think could have an impact:

M92 X50.929 Y50.929 Z50.929 U50.929  E50.929               ; Set steps per mm

M201 X1100.00 Y1100.00 Z1100.00 E1100.00                ; Set accelerations (mm/s^2); 
M906 X700.00 Y700.00 Z700.00 U700.00 E500.00           ; Set motor currents (mA)
M84 S0                                             ; Disable motor idle current reduction

Thanks for your help...
