If I wanted to tilt the bed on a tool change with a chimera to give one side some extra room would I need to disable the mesh bed and re enable it after the bed movement or is there anything else. (Dual independent Z). So in tpre I want to lower one side and then in tfree I want to bring it back to normal. Just to experiment. Im on RRF 3.1.1.

Will this work https://images-na.ssl-images-amazon.com/images/I/71LSxfU8%2BFL.AC_SL1000.jpg

I got this https://images-na.ssl-images-amazon.com/images/I/81YyEdQAhCL.SL1500.jpg but it looks like it does not work with the 2208. it says it works with A4988 DRV8825

I want to add a volcano also witch will make 7 tools.

Am I getting close on trying to not tool change with a chimera?

I got .001 on one set of leads and .003 on the other. I had it set to ohms where it beeps. i got a beep on both leads. thats at the end of the extension wire threw the connector.

I have the M906 set to 400 now cause i didnt know the best way to reduce it before i ran the homec. I know it reduces after an unlock or lock. do i put an M913 after the M906 in the config.

Is there another way to reverse the motor.

I dont know how to link a thread but i tried this allready.

If your C motor will only go one way, it could be that one of the phases is disconnected, because of a burned out motor winding, bad crimp connection, or faulty driver on the Duet. Try the following:

Use G92 followed by G1 H2 Cxx moves to test the motor and driver, with both positive and negative C values
Measure the resistance of the motor phases between the pins of the Duet motor connector (with power off of course).
If they look correct then try swapping the motor output with anther one, using M584 in config,g to swap them in firmware too (don't forget to swap the values in the two M569 commands too).

except the resistance. Do I just check to see if the have the same resistance.

I order a new motor. wont hurt to have a spare if its not it.

also when i had it at 60% it only turned 1 direction but when i went to 70% it went both ways but still backwards.

Im all over the place. I changed to 8 to see if it was the driver, just said it wrong. is that supposed to change the direction? Im rustry i first built my printer over a year ago.

I would try adding .05 or subtracting to one of youre leadscrew distances (M671 X-116.05:322 Y100:100 S4 ) and then see if you get a better score. or maybe .5

Might be you're probe. I use an original bl touch.

What are all the ways I can try to change the motor direction. I tried changing the wiring and changed the M569 P7 S0 to S1 and tried changing my endstop from high to low with.
I am having trouble homing my c coupler. I think im over heating it. sometimes i can trick it and make it unlock and lock but after 2 or 3 it starts acting like an extruder and only goes one direction

Board: Duet WiFi 1.02 or later + DueX5

I can get down to .o3 . You can make a macro with you're bed.g.
dc42 said this in another thread.

Copy your bed.g file to another macro file; then change the S parameter on the final G30 command to S-1 to get a report only when you run that macro.

I had that problem at first and it was I had both my z motors connected to the same z driver. I needed to switch one to a separate driver. I use driver 2 and 5 Z2:5 depending on youre firmware you might need a u axis.

Yes that was me.This is awesome thank you. I do have the duex 5 and WiFi but I am going to get a duet 3. I have 2 printers I am converting. Im struggling with the C coupler. I posted on the e3d forum,

I cant get my C motor to go the right direction. I tried doing a G92 C123 and doing a C33 but the motor always goes the wrong way.I changed the wires on the stepper and changed the M569 P7 S1 and S0 but it always go the same direction. I tried homing C (stall) and M92. What is the best way to do the M92-- should i start it at 0 or go to unlock at 123 or go to 33 lock?

what external steppers should I use? extruder . I am not good with a soldering iron.

If its easy can someone get me started on the conditional G-code to not pick up or dock a tool with a chimera?

I have it working really good. I just know that my distances to the lead screws are just a close reference and I think that's where the small error comes in when doing a G32. I think there is a formula that will figure out what the true distance is, It might only have to run g32 once. Maybe save the new distances in the pid folder(M501) I love the way it is now. It might be easier to set one lead screw as a pivot point (dual independent) instead of X0 or Y0 if a formula would work.

I think I can only get so close with my distances to the lead screws for the g32 level.(dual independent) I think I saw a thread were dc42 might have been talking about it but he used words I didn't know. There should be a way to run the g32 then it adjust the lead screw distances to get closer and repeats till its perfect. I was thinking i could do it with conditional gcode but now i think it has to be in the firmware.

@dc42 I am running a chimera and I think my main concern is having the x axis the closest. I set my nozzle heights after I get dialed in. Its been working really good. It also seems like if I had a single nozzle it would be better if I could get it super close in 1 axes and close in the other. Rather then really close in all axes.
