@droftarts I think I understand. That's huge help. I'm going to look into some new motors with lower inductance. Thanks for explaining it!

@Phaedrux They sound like they've got sand in them.

I'm using a Duet 3 Mini 5+ board with firmware and DWC version: 3.5.0-rc.2 and Duet WiFi Server: 2.1beta4 on a cartesian frame.

The problem I'm having is my stepper motors are grinding and banging and I'm having probelems with layers shifting. I think it's related to my Creality stepper motor settings. So I was going to start there. They're all Nema 17s. I'm using 2 x 42-40s on my X and Y axis, 1 x 42-40 on my extruder and 2 x 42-34 on my Z axis. I'd link to the datasheet if I knew where to look. I've found so many and there's so much contradiction between them that I didn't know which are applicable and which aren't. So, sorry for that. My printer was originally a CR-10S and that's where the stepper motors came from.

I've spent the last couple of days trying to figure out exactly how to set the values for these motors for Stealthchop, etc. I've hit a wall and have given up sorting it out. On the tuning page, it seems like you need to know what you're looking for already to put the values in. I have no idea what to test for or how to test. I looked at the EMF calculator page but I couldn't tell you what to do with those values or what they represent.

I have to be honest. I really like not having to flash the firmware everytime I'd like to make a change, but I'm hitting so many walls when it comes to configuring this board that it's beyond frustrating. The major problem I have is that most of the guides/instructions/discussions I can find are full of non-standard terms, acronyms, slang and written with an assumption of a very high level of knowledge. I'm finding it impossible to sort out things out without a herculean effort. The basic instructions are great, but I found I was out of my depth really quickly.

@OwenD said in Need some guidance on pausing a macro until I provide input:

M291 R"Wait" P"Check bed height. Press OK to continue" K{"OK","Abort"} S4if (input == 1) echo " cancelled" M99

Thanks so much! I'm using firmware version 3.46 (I'm not aware if 3.5 is stable enough), so I had to change it a little bit. I couldn't go higher than S3 and it wouldn't accept the "input" value. I ended up using the following:

G1 H2 X30 Y30 F6000

M291 R"Wait" P"This is a pause. Press OK to continue" K{"OK","Abort"} S3

G1 H2 X50 Y50 F6000

This works great so far! Thank you again!

I've got to be missing something. I'm trying to run the following example code:

G1 H2 X30 Y30 F6000

; insert macro pause here
M25

G1 H2 X50 Y50 F6000

However, it always returns "Error: Cannot pause print, because no file is being printed!"

I'm not printing anything. I'm just putting a macro together to level my bed and need to pause so I can check the bed height. After I've done that I'd like to continue the macro by clicking resume (or something similar). I've tried M226 as well and, although I didn't receive an error, it didn't have any effect. I'm unable to use G4 because I don't know the duration of the pause.

Any guidance would be appreciated.

@dc42 You are absolutely correct! I don't know why I thought otherwise. Thanks!

I'm using some nested macros and I'm having issues where, when I'm in relative movment mode, the machine returns to absolute movement becaue I've called a macro that has the G90 command. I'm wondering if it's possible to issue a single relative movement command (eg. G1 Z20) in absolute movement mode without using G90 and G91. Alternatively, is it possible to set the value of inputs[0].axesRelative to a variable value like set inputs[0].axesRelative = {RelativeMoveVar}?

I've tried using M120 and M121 but it also affects feedrate and hotend position.

@infiniteloop Thanks! Let me play around with this for a bit and see if the problems fixed. So far the X axis isn't rapidly switching...

@infiniteloop That's right

@infiniteloop I really appreciate the help. Thank you.

Here's the photo...

The improper axis movement does still happen. I believe what it is is when homing the axis, it initially doesn't check to see if the endstop is triggered and moves away from the home position. Then, after moving away, it checks the endstop trigger and if it's registering as triggered then it stops where it is.

It seems like all the problems happen much more frequently with the X axis then about half as much with the Y axis and only occasionally with the Z axis.

@infiniteloop Here's the config.g file.

I'm sorry about the lack of understanding of the terminology. Electrical isn't my forte

The wiring is the stock Creality CR-10s wiring. It worked fine until I set up the new board. I've tested it all for continuity and there's no problem with that.

I hate to admit it, but I really don't understand enough to figure out the rest of your message.

What would the best way to upload my config.g?

@fcwilt I don't know what the brand is for the endstops but they're the stock Creality CR-10s ones. Here's a picture. They're connected through the original Creality wiring. I've tested with different endstops from another printer that's working. Same issues.

I've got a Duet 3 Mini 5 with the firmware etc.: FIRMWARE_NAME: RepRapFirmware for Duet 3 Mini 5+ FIRMWARE_VERSION: 3.4.1 ELECTRONICS: Duet 3 Mini5plus WiFi FIRMWARE_DATE: 2022-06-01 21:07:06. This board is running a Creality CR-10s printer. It's stock except for a E3D V6 Volcano.

I'm having a problem with the X, Y, and Z endstops working intermittently. I was having problems with homing initially. At times the hotend wouldn't move in the home direction. It would simply move further along the axis away from home. And then it wouldn't. I'm using your "Endstops Monitor" plugin. It shows the X axis flickering as homed on and off randomly. Probably 1 or 2 times every second or 2. The Y axis is doing the same thing but not as frequently. And the Z axis is even less frequent.

I've tested all the wiring and the endstops themselves. I've tried different wiring and different endstops. I did notice that, for a while, the X axis endstop was doing the same thing without anything connected to the boards X endstop connector. And then, after awhile, it didn't.

I can't print with the hardware in this state. It's too unreliable. I'm out of ideas and beyond frustrated at this point.

I'm not sure if this is specifically where I look for support from Duet3D, but I figure it's as good a place as any. I'm really hoping it's more helpful than their documentation.

@aurimas I've been having the same problem... Check this post out...

https://forum.duet3d.com/topic/28218/cr-10s-heated-bed-error-temp-rising-too-slowly

@phaedrux I really appreciate your help with this... Thank you!

I haven't received the heating too slowly error since I tried tuning again. I added a basic PID value before I ran it. I think that made the difference.

When I say it's heating really slowly, apart from the error, I mean complared to the same printer with the original main board. It's the stock heater bed.

I'm running a tuning cycle right now. I'm including the screen cap of the process during Phase 3 at 19 mins in.

@phaedrux I appreciate the advice, but I've tried a couple of time to run "M303 H0 S60" a few times. I even left it running over night. It just never finishes. I know I've got 12v to the bed and when I run "M303 H0 S60" the bed gets hot and the thermistor registers the correct temperature. I have no idea how to get it to finish.

Any other suggestions? Or maybe you know where I could get a preconfigured config for a CR-10s?

I've replaced the main board in my CR-10s with the Duet 3 Mini 5+.

I'm having a hell of a time configuring this thing. I've been at it for over a month without extruding a mm of filament. Most of the info I can find is either incomplete, isn't informative about my hardware, contradictory or assumes intimate knowledge of all of the variations of RepRap gcode. I'm beyond frustrated so excuse me if I come across as annoyed...

My latest in a string of difficulties is that when I try to heat the bed to 55c I get the following error:
"Error: Heater 0 fault: temperature rising too slowly: expected 2.31°C/sec measured 0.18°C/sec"

It's always some variation of that. I'll include my latest config.g file.

config.g

I'm really hoping someone can help me. I really just want to use this paperweight...

[Edit] I should mention that I've tried tuning the bed heater with "M303 H0 S60" but it wouldn't procede past "Auto tune starting phase 3, measuring". I left it on all night. There were no errors or anything. It just sat there. I powered it off and on and everything seemed the same.
