maximum instantaneous speed changes
that is jerk in marlin. you are basically saying you can instantly go from 0 to 250mm/sec

X2 is not valid here. where did you connect the thermistor?
ok i give you that its valid, but its very unusual to specify this here.

@thejmather said in Trouble with the Duet 2 on a Monoprice Maker Ultimate:
I had to use the 2.x firmware in order to get the endstops to read correctly. From the factory they seem to be wired up for Normally Open, which the 3.x firmware didn't seem to like at all.
That's a pretty easy fix. You just need a ! in front of the pin name to invert the signal. Since you are new to reprap firmware I would suggest giving RRF3 a try. It's more flexible and capable and still being developed long term.
If you post your RRF3 config.g we can help you out.
It looks like you figured out your layer skips though. It's important to mind the units. mm/min versus mm/s. Convert by multiplying or dividing by 60.

Ahhh! Ok, that'll let me convert better. It seems like these tweaks mostly worked.
I'm still VERY confused why the Wanhao controller works with 400.48 steps for Z axis but the Duet 2 needs 800.96 to work right. I double-checked the cables last night and all of the wiring for Z matches X and Y. So weird.

Microstepping will also come into play in calculating steps per mm.
Z_steps_per_mm = (motor_steps_per_rev * driver_microstep) / screw_leadThe recommended default for the Duet is x16 microstepping with interpolation to x256 by the driver chip. So you would calculate based on x16. Maybe the microstepping for your old board was different?

Everything I was able to find said ~400 is the right answer... and most things seem to suggest the D6/MMU has 16x microstepping, which means it's a Tr8X8 screw... I dunno. It works, so I'm not really inclined to argue with it, but it sure is BIZARRE.
I can look at the Marlin firmware tonight and see if it specifies the microstepping anywhere... the up side of having installed the BLTouch previously, I guess, is I have the source code handy... lol.
I haven't been able to find a good reference for understanding /for sure/ which motor pins on the Duet go to which motor pins on the motors, but it seems odd that the Z axis motor would just be wired differently, too... so it's hard to say.

I'm pretty sure I tried the ! trick, but if I can get it working with V2, then I'll give V3 a shot again for good measure now that I feel like I know a bit more about what I'm doing.

So trying to get the same config on V3, I get:
M574 X1 S1 P"!xstop" ; configure active-high endstop for low end on X via pin !xstop M574 Y1 S1 P"!ystop" ; configure active-high endstop for low end on Y via pin !ystopand that ends up reporting that the endstops are triggered... which is the same as I get if I remove the !'s.
I also can't get the Z-probe to work with this setup. Followed this guide with the exception of using Heater3 instead of Heater7.
I am going to throw the 2.x firmware back on and print a calibration cube and see where I'm at on that front...

Identify the phase pairs, then each pair goes together on either side of the board pins. As long as the pairs aren't crossed it doesn't matter which pair is on which side. You can change motor rotation direction in config.g.

Endstops read as triggered when they are not.
Then remove the ! from the pin name.
How do you have the endstops wired? Are they standard 2 wire endstops, or 3 wire with a PCB?
https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches
2000c on the temp would indicate a short circuit fault. Which heater pins are you using? Your config says e1temp, but e0temp would be the first temp sensor. Which one are you plugged into?

What exactly doesn't work? Did you also change the deployprobe and retractprobe macros to use P0 instead of P3 or P7?

With or without the !, it reads as triggered on V3 firmware.

They are 2 wire normally open.
This config works fine on the V2 firmware.
M574 X1 Y1 S0 ; set active low and disabled endstopsAm I going to need to change how they're wired up for the V3 firmware maybe? I think I have the lines connected to the two outside pins of the three pin connectors, but I'd have to double-check that.

I apparently had it plugged into the E1 thermistor spot before... I moved it to E0 and it works as expected on the V2 firmware with
M305 P0 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 0 M305 P1 T100000 B4725 C7.060000e-8 R4700 ; set thermistor + ADC parameters for heater 1I tried the config a couple different ways, even after moving it to the E0 input and setting it to E0temp, it still wouldn't work. Both still read at 2000 on V3.

Yeah, I fixed all that, and even tried manually sending:
M280 P0 S10to which it responds with "servo 0 is not defined" (or similar -- i'm printing a calibration cube on v2 firmware now or I'd check).
-
Servo 0 not defined would make sense if you're still using rrf2
Can you send m122 and m98 p"config.g" and post the results ?
It would be a lot easier if we just configured for rrf3 at this point.
-
How are you switching between rrf2 and rrf3?

This is the million dollar question... for some reason, I had thought that just uploading the config zip file was enough.
Your last comment lead me to check my assumptions, and yeah, it's still running 2.x...
I'm trying to upload the bin via the web control panel now... I've managed to get web control panel to report that it's 3.x but diagnostics is still saying reprap is 2.05.1...
Do I have to do a hard power cycle maybe?
-
Ah, ok, then. That answers that.
Here's how you should proceed with the updates.
First make sure you're running 2.05.1, and it sounds like you are, but just to make sure you have all the files needed here's how you do a complete firmware update. It just involves uploading a single zip file for each version to the sys folder via the web interface.
Start with the 2.05.1 zip file. Then upload the 3.0 zip file. Then 3.1.1. It'll reboot between each. Then you can upload your config zip file if you haven't already.
Upload the whole zip file. don't extract it.

Alright! This seems to be working a lot better. It got to 3.0.0 successfully, though it's been spinning for quite a while on 3.1.1.
The temp sensors were working though.
Still just waiting on it to come back up after the 3.1.1 upgrade though. Might have to go a more manual route for this one since it seems to not be coming back up...

should take less than a minute; reset and try again if it takes longer.
