Alright that seems to have fixed it.

@dc42 Thanks for all your help!

The Z driver is still acting how it did before. The E works with the M code commented out, but not when the M code is active. The M code is at the top of the config.g file and is only preceded by the network setup.

@dc42 Thanks for the response. I confirmed a bad crimp on the Z motor, so I believe as much as I have used the printer (before this behavior developed), I probably messed up the Z driver. However, the E motor did not have a bad crimp. In an effort to get all the information I thought helpful for troubleshooting, I probably made the issue with the E0 motor more confusing. I also confirmed the power wires were still tight.

With the E0 motor, it worked fine before switching the Z motor to E1, but not after adding the M584 command to the Config.g file and putting the Z motor in for E1. It then worked as expect after commenting out the M584 command. I have not tried another motor in its place but with the crimps and pins being good, I believe the issue is a mistake I have made in the use of M584. I am open to that not being the case however. As far as using M584, that is the only thing I changed to try to use the E1 driver for Z. The printer was originally setup to E1 and E0 for extruders (I have not got around to experimenting with dual extrusion so I am OK with losing that possibility for now to gain a working print again). Any ideas?

Thanks,

All,

I have been experiencing some odd behavior from my Steppers and have run out of ideas for troubleshooting. I was hoping some of you could help.

My machine
Is a Seemecnc Rostock V3 (a Delta style Printer) which I have upgraded with: stepper dampers, Duet, Panel Due, FSRs, and an E3D V6 Nozzle (removed the original z probe entirely). I also put this machine in an enclosure with the top (area with Duet) open on one side and a similar thing with the bottom (where power supply is).

Problems
So I have been printing on this machine with few issues until the past few days. I started the machine up and tried homing it and I got a loud grinding noise from the Z axis and no motion from that axis (X and Y axis seem fine). So after plugging the Z motor in the Y driver the Z motor ran fine. Next I found and decided to just map my one Z motor to E1 since I do not use it. The Code I used to do so:

M584 X0 Y1 Z4 E3

Afterwards the machine homed with out issue. So next day I started the machine and homed it fine, but when I went to change out my filament (E0) the stepper made noise and jiggled back and forth some but did not move the filament. After commenting the M584 code and trying it again it worked with out issue, I tired putting the Z in its normal spot and it still acted how it did. I tried updating to 2.02 and the problem is the same.

I do not exactly know where to go from here. I assume the issue is something with the Duet hardware or software , but I do not know what to look for. Attached is the config.g file I am using. Any help is appreciated.

@dc42 Thanks

@SnowCrash I would be interested in collaborating if there is some way I could be of benefit.

Danal, for right now I think I could get away with just polling the Duet.

dc42, I am having a hard time finding SDA and SCL on the Wiring diagram, are the called something different?

Thanks

I am curious if there is a good way to have a Duet 2 communicate with another board (Say an Arduino)? What pins would I use?

Reason for doing using a second board other than Duex
I am building a cabinet in which I am going to put the printer with the Duet. I am planning on a making it have a heated chamber, with several lights, fans, and maybe some servos. When I add up all the PWM pins and everything else I would not have enough between the Duet and a Duex 5. I do plan on running essential fans (like hot end, part, and Duet cooling) of the Duet itself though.

My Background
I am a Mechanical engineer with less than 1-year real world experience. I am comfortable building things, but have limited programming experience (C and MATLAB, mostly limited to a Classes and a small “light switch” project). I am more familiar with wiring, but appreciate extra info. I am using this project to learn and grow, as well as to get a nice printer/cabinet combo.

Thanks,
