Great, glad you got it working.

the guides are actually the same so is the link.

I know, I wrote both! The Dozuki wiki is the old wiki and hasn’t been updated for over a year. Use the new wiki.

@dc42

Thank you!

@Phaedrux Thank you I believe this did the trick!

@Feynman137 said in When I pause during a print, printer does not home correctly:

@Phaedrux you are correct the homing file is hitting the limit switch then moving away from it just slightly. There is an unprintable region due to the dual nozzles and bed clips etc.
The X0 and Y0 should be a safe place after the homing has been completed.

When you do that, the axis maxima is also shifted over. That would explain it if it were crashing into the high end of travel, but not why it would crash into the limit switch on the low end.

It's safer to use the method mentioned by OwenD to use an altered minima instead.

Perhaps a video of the problem in action would be helpful.

@OwenD said in When I pause during a print, printer does not home correctly:

(Not sure why you have a negative Z minima)

A slightly negative z minima allows you to baby step lower than z0.

@Feynman137 In addition to what @OwenD has said, be careful about the terminology. Pulse Width Modulation (which is what PWM) stands for essentially means turning the suppyly voltage on and off in pulses. The PWM value is essentially the ratio between the on pulse and the off pulse. So a PWM value of 0.5 means that the on pulse will be equal in time to the off pulse. A PWM value of 1.0 means that the fan will be permanently on. The PWM frequency is the number of cycles per second. If the requency is say 100Hz, then one cycle will take 10 milliseconds. If the PWM value is 0.5, the the on time will be 0.5 milliseconds and so will the off time. If the PWM value is 1.0, then the on time will be the full 10 milliseconds.

G30 S-1 is typically used to measure your probe offset.

G92 Z would be used to force a certain position, which kind of defeats to purpose of the probe.

Use a single G30 to probe, and you're good to go.

@feynman137

It appears the issue was incompatible firmware between the expansion board and my mainboard but I issued the M997 command and now I can turn on the heater.

Ah you guys were right. I actually faced an issue with my old raspberry pi where even when it was wired via the ribbon cable the web server would spend forever connecting. So I assumed the new rpi board would be able to connect without the duet board.

Once I wired this rpi to the duet mainboard the duet web server could load in my browser.

Thanks!

@phaedrux I just decided to drop in a new mainboard 6hc will fix this one later by replacing the ICs suggested. I am running using a raspberry pi 3B+ and figured I could just swap all the wiring to my new board. Is this correct? I have backed up all the files from the old board just in case.

You'd have to pass that through Cura start gcode and check the sliced file to see if it evaluates correctly. Then try manually sending the command (with a real number for temp) and see if that does what you expect.

As always, a bit more information about your machine would help understand the problem. Physical setup, intended use, configuration files, ...

@feynman137 Oh YEAH! I forgot you need to start it up.

Settings->General Click "Integrated plugins" tab then start it.

@feynman137 said in Connecting to duet mainboard 6hc with new computer:

I do wonder is this secure though?

Secure how? It's only accessible from your internal network unless you make the effort to open it up to the outside.

Use G30, not G30 S-1.

G30 is a single probe to find Z0.

G30 S-1 is to determine the trigger height of the probe when z0 is set manually.

To control the speed of the probe move you need to adjust your M558 command in config.g which defines the probe behaviour. The F value is the dive speed.

@dc42 said in How to define print bed area versus M208:

Avoid using G92 if possible because it will mark the axis as homed even if homing

In the example I gave if homing failed would not the "plain" G1 move immediately preceding the G92 also fail thus preventing the G92 from being executed?

@fcwilt
Yea each stepper has its own driver all of the drivers are tied to the z axis in the config file.

I think the auto bed leveling is exactly what I am looking for, but I just need to do some reading to understand how to do this with my set-up.

@phaedrux @fcwilt Thanks for the M140 P comment I have added this to the code, and made the other described changes it should be up to date.

Occasionally the expansion boards don't get updated automatically. I think that is being improved upon.

Regardless, it's also a good idea to check the installed firmware versions after an update with M115 and M115 B# for the expansion boards.

I would suggest that you do a sudo apt update and sudo apt upgrade again just in case. Ideally you'd only have to do that once for each major release going forward.

@dc42 The cable did the trick sir. Thank you for your advice!
