Not all stepper drivers working
-
Hi all. Im fairly new to DUET3 but I'm familiar enough with it. Im working on a hangprinter and after testing the motors individually using the g1 command, I have come to suspect that 2 of the 6 stepper drivers do not seem to be functioning correctly. The 2 "faulty" drivers rotate the motor much slowly and sound slightly different than the correctly working ones. All drivers have the same exact settings so i don't know whats wrong. The command i send to each motor is g91 and then G1 H2 Z-5 and for x Y and U respectively. Every motor responds fine except the Z which was tested on driver2(as per config) and driver 5. I know for a fact its not the motor because i tested different motors on that same driver and get the same result.
From testing the drivers, it seems drivers 2 and 5 are not responding correctly and seem faulty. Is there anything I'm missing in software or is it indeed a faulty driver?
I have posted my config file below. Note: it is not complete yet and I'm only concerned with getting the motors working individually right now.; Enable network

M84 S30 ; Set idle timeoutYou may be having some problems by having the extruder config before the rest of the drive commands. Rather, there is an order of operations for some commands. Especially for commands that refer to axis.
M584 must come earlier in config.g than any M350 and M906 commands. If it creates new axes, it must also be earlier than any M92, M201, M203, M208, M350, M566, M574, M667 and M669 commands.
Try cleaning that up and try again. Maybe use a generated config file from the config tool as a template for the order.

@phaedrux ah. That makes sense. I will try and report back. Thank you for the suggestion. Another thing I haven't tried is actually remapping another axis to the "suspected" driver. I'll try these fixes and let you know. Much appreciated for the prompt response.
-
@phaedrux So ive tried what you've suggested but I still get the same result. The driver to which the C motor (zaxis) is connected still goes slowly than the rest. I have also tried the following file generated from the config tool (basic cartesian mode). I set all stepper drivers to the exact same settings but I still get driver 2(Z-axis) to move noticeably slower than the rest. I set to incremental using g91 then I send the command "G1 H2 Z-5"

is there any way to tell whether or not the drivers are bad?

They all have exactly the same settings so should move the same when jogging through DWC.
I'm assuming they aren't connected to anything.
Either use M564 H0 so set each axis to an arbitry value using G92 -

Originally, this is supposed to be a config file for a hangprinter but right now I'm just trying to find the cause of why that certain driver was slower than the rest in my original config file for the hangprinter which I pasted above.
-
@ravs99 @jay_s_uk Hey. Thank you for the suggestion, that particular driver does seem to be rotating at the same speed now! However I need to make sure to apply this to my hangprinter config which I've posted above. It does seem to be an issue in my configuration so I will look into it. Thank you for the help so far.
-
@ravs99 good news. hopefully you get your config sorted
