@bartekp said in Homing testing issue:

@bartekp what I mean dosnt work tha that when I use home all Z make problems when I change the -605 Homing z Make problem and when I start printing Z goes down

Well that G92 Z100 command tells the firmware that the current position of Z is 1undefined00 - which is likely not correct.

When a G1 H1 command triggers and endstop it sets the current position for the axis to the axis min/max value as set in M208 for that axis.

If the endstop is configured to be at the "high end" of the axis the value used is the max value from M208.

If the endstop is configured to be at the "low end" of the axis the value used is the min value from M208.

It is common for an endstop to trigger at a position that is somewhat different from the min/max values in M208.

In that case you can use G92 to "tweak" the logical position of the axis to match the actual location of the endstop.

Let's say your X axis min/max values are 0 and 300. Let's also say the "high end" endstop triggers at 295.

So G1 H1 X300 would trigger the endstop at 295 but the logical position would be set to 300, the max value from M208.

So then you could follow the G1 command with G92 X295 to set the correct logical position so that the full range from 0 to 300 would move from the low end of the axis to the high end.

If you use G92 it is up to you to determine the actual value that represents the position where the endstop is actually triggering.

So I don't know why you have G92 Z100 but it is most likely wrong - by a lot.

nd the 120r is onboard and i have to set the solder jumper?

yes

@petrkroupa thanks for the suggestion. I have moved this into the firmware wishlist section.

@t3p3tony Still don't know the specific model. It needs to be 10-15mm travel and about 5N force.

Something like that:

@jay_s_uk okay, I will try to update the firmware and see, will it help

Hi Frederick! @fcwilt

Very good news, you found the solution! 🙂
I applied your suggestions and now the issue is totally fixed!

Thank you so much for all the help provided.

Julián.

Glad we were able to sort things out.

Hi,

Here is a link to a quick-and-dirty video showing the mini linear guide at work.

Mini Linear Guide At Work

It was hard to get a good view - sorry.

Frederick

Just a wild guess here, but perhaps RRF uses negative values in that context to indicate deceleration vs acceleration.

That, or the lookahead queue is being overrun and the move can't be adjusted (or whatever happens), causing the time to be invalid.

@droftarts i'm totally blind, didn't see that. Even if it still says error heater 7 not found now m401 and m402 works! Thank you very much again

@bartekp
im back to the homing , still is some thing wrong because I try to print some sample ,when ar homed all axis I set the print and as always printer start homing and at the end the z axis go down to the max low position I men down I give up

I some starting procedure ??

@t3p3tony said in NEMA 17 24v power off Brake on D3 Mini:

@cncmodeller they would both be on the mainboard in this case so for example
M569 P3 C"out2" ; driver 3 on mainboard uses port out 2 on mainboard.

👍 got it. Many thanks. 😀

@diamondback

Published Beta 0.9.04.

Changes:
Fixed Text & Machine Model panels issue when used in custom panels.
Enabled ability to hide the panel border for custom panels in layouts.
Fixed right click menu issue with DWC Webcam Panel.
Removed redundant text orientation option in Text Panels - Text auto word wraps.
Reduced padding on Text & Machine Model panels, so panels can be made smaller.

@thechainring see https://duet3d.dozuki.com/Wiki/Laser_PWM_control#Section_Controlling_the_laser. Mode programs for producing GCode for laser cutters/engravers support controlling the laser using the S parameter of the G1 command.

@Tinchus I just saw your other thread where you say:

But I tried to start printing today and I found this issue: so far I was using the DWC, on the screen I choosed the desired temperature. Due to restrictions or maybe my lack of knowledge on reprapfirmware, my config created on the screen 2 chambers, so on the screen I have to set up the chamber temperature on both of them. No a problem for me. And this is working ok. I set up the temperature on them and both resistors turn on.

Now I moved into printing. I set up my start gcode using M141 P0 S80 and M141 P1 S80 in order to turn on both chamber heaters.
To my surprise this gcode is not working : M141 P0 S80 turns on 1 heater, but them M141 P1 S80 turns on the other heater but turns off the first one. And so on: every time I execute a gocode to turn on 1 heater the other one is turned off.

Lets keep the discussion here so its easier to follow later

Ok so this has progressed to the point where the two chamber heaters work when controlled with DWC, but not in a print file?

I have replicated part of your system as best I can (I dont have a chamber with two heaters so have to work around this) and If I send:

M141 P0 S150
M141 P1 S150

from the console, both heaters stay on (at least until the heater faults i get beacuse this is not a proper chamber heater just a replication).

Can you try sending the commands form the console and see the results.

If the first heater turns off then are any errors reported in the console? Also what is the state of the heater in DWC?

@sniper23 fair enough. as you are then

@cjm I have read through that thread and still dont quite understand where to put the resistor. Is there a schematic or a picture of where it should be anywhere?

if you change the flavour, the settings tab for all the speeds etc comes back and you can fill them all in.

In my case this menu not appears, but I will look what is going wrong.

found it 😄 the Machine limits are only showed if Marlin is selected

@t3p3tony said in Bed heating starting with lag:

What is the rating of the heatbed you are using?

It doesn't say. It's a 24V PCB bed that came in this kit, but I can tell you that the power draw from the mains during bed heating (according to my Gosund P1 smart power socket) is ~400-430W with a 24V PSU and a Duet-only 5V PSU. I guess it's rated at about 350-400W.

While the heater is in the initial flashing phase, is the mosfet getting noticeably warm to the touch?

Is that the one right next to the fuse and the bed heater terminal block? If so, it stays cooler than my body temperature until the bed actually starts warming up.

Another test you could try is temporarily switching the bed heater out for your extruder heater. swap the temperature controls as well and still control the bed heater as a bed. the idea is to see if it behaves the same way with a different (lower) load.

Got it. I can't do that now, but I will try soon.

Thanks for helping me debug this!

@joergs5 thanks... I will see

@cosmowave yes thank you 👍

ah yes this makes sense thanks @gloomyandy !

@tom33 Thanks, no I understand what you mean. Just to make 1005 sure we are on the same page, you can't control a heater with M42 if you have already mapped it to a heater. Can you send the following (with nothing plugged into out2 and out2 not used in the config.g

M950 P20 C"out2" M42 P20 S1 ; LED on out 2 should come on M42 P20 S0 ; LED on out 2 should go off

Make sure you use "run as administrator" when starting Balena Etcher on windows.

It may fail otherwise.
