@adistr have you tried playing with the steprates / u-step settings in the config?
in theory you could give one motor assignment twice as many u-steps as the other and it should more 2x as fast if the same deg/step as the other motor.

@alankilian You even said to use trigger 2 in your original reply... https://forum.duet3d.com/post/284007

@adistr said in Using endstop for DC motor:

M581 T1 Y S1.

Why is the trigger not executed and the DC motor continues to run?

This looks like syntax for RRF2. Surely you are on RRF3.4 now which is far more felxible?

@adistr said in connect my Python application to my Duet2 wifi printer:

Are there examples of connection via IP in favor of connecting with a duet 2 wifi?

I didn't search the forum on that. Have a look at DWC related topics, also, there are several posts about plugins and HTTP requests. Here's a link to DWC on GitHub. I didn't find a comprehensive link to the Duet web server, though.

I'm guessing this isn't a printer application?

Have you reviewed this document? https://docs.duet3d.com/User_manual/Reference/Gcodes#introduction

The first sections give some idea on how gcodes are processed, and the G0/G1 commands explain how movement is carried out.

What kinematics are you actually using? The default assumption is a cartesian system with an X, Y, Z, and E axis. Movement is coordinated by the firmware to complete the move in XYZ space at the fastest feed rate allowed by the individual axis up to the specified feed rate.

Homing moves are also a particular case, in that movement is started and carried out for the distance specified up until the endstop is triggered.

You've asked a number of fairly specific questions with only a vague idea of what is actually required to happen. Without more details about your endgoals and setup it is hard to recommend solutions.

@phaedrux @deckingman thanks for the additions!

@fcwilt Thanks

Can you be more specific?

@adistr What is the full command you are using to tune the heater? What happens? Do you see the heater temperature rising (maybe post a screenshot of the temperature graph just after the tuning fails). You should probably also post your config.g so folks can see how you have things set up.

If you write a short gcode, you can test to see if this is a dead-band issue in the servo. Try starting at zero, moving to 95, then 100, for example. Then, go back to zero and move directly to 100. See if you end up in the same place. You may have to adjust the number to see the dead-band.

Long and short moves on a servo can end up at slightly different places, unless the dead-band is set to zero, in which case the servo tends to vibrate when it is supposed to be holding.

@adistr you can use this form to apply different temperature settings to the two heaters:

M568 P0 S260:230 R150:130

@adistr it's 1.5A each. If you are using the 12V regulator to power the fans then there is also the regulator limit for the total fan current, 2A AFAIR.

Works great, thanks a lot

@adistr ??

@rjenkinsgb
Great, thank you very much!

@droftarts
It works according to your example, thank you very much!

@dougal1957 thank you!

@dc42 Thank you!
