Help with new setup please

troydeming

I just got a replacement duet wifi2 board and upgraded it to reprap 3.5 I am setting it up and am having difficulties getting the axis right. It isn't letting me home them. I have a Folgertech FT-5 with Duet wifi 2 board and a BLtouch. Any help is appreciated

@troydeming

So when I try to home x using g29 x or hitting the home button or the home all button the x will move in the correct direction but stops after about 10 mm.

You don't use G29 to home, you use G28.

Please post your homing files AND be sure and use the </> tag to paste them right into your post so we can all see them without having to download files.

I meant to say g28 dont know why I said g29.

@troydeming
I just saw the following error on startup.

Error in start-up file macro line 58: Pin name needed for switch-type endstop on Z axis

droftarts

@troydeming said in Help with new setup please:

Error in start-up file macro line 58: Pin name needed for switch-type endstop on Z axis

That's due to this line:

M574 Z1 S2 ; configure Z axis endstop

Though I think you may have changed this from S2 to S1? Either way, it's not needed if you use the probe for homing the Z axis with G30, so delete the line, or comment out the line with ; at the beginning.

Are you still having problems with the X and Y axis homing? Maybe repost your config.g if you have made changes to it.

Ian

@troydeming

I see you compute various values, example var.maxTravel, and then don't use them.

Did you at one time use them?

Now this is just me, my two cents, feel free to ignore because you don't talk to crazy folks - On all of my printers I install a Z end-stop sensor for homing Z, which means I don't have to home X and Y first, which must be done so the Z probe can be used for homing Z. Being able to home Z first also means, when homing X and Y, I don't need to jog Z out of the way with those G1 H2 moves, which under certain circumstances can drive Z against end of the axis, which makes unpleasant noises, which upset my dogs.

Just to be sure we are all on the same page, what is the issue you are having with homing?

Frederick

troydeming

@fcwilt
when I home x the carriage only moves 10-20 cm then it stops and the bed then rises 20 cm

Can you jog each axis (X Y Z) separately from the DWC jog buttons?

You can use this command to allow jogging axes that are not homed:

M564: Limit axes
Parameters
Hnnn H1 = forbid movement of axes that have not been homed, H0 = allow movement of axes that have not been homed (firmware 1.21 and later)
Snnn S1 = limit movement within axis boundaries, S0 = allow movement outside boundaries

If you can jog each axis separately have you verified that jogging a certain amount from the DWC actually moves the axis that amount?

Frederick

troydeming

@fcwilt
Thank you for that I am able to jog them now. Now I found out that when I jog X the Z is moving. I double checked the wiring and its all correct. So now I am going down the rabbit hole of why the two are crossed in the mapping.

I am showing right now.
;M584 X2 Y1 Z0 ; set axis mapping

It seems right to me but is it?

troydeming

@troydeming

I just looked it up and I have them configured backwards.

fcwilt

@troydeming

That might make homing not work quite right.

Frederick

troydeming

@fcwilt

I got it working finally. Therre was a fault in the wiring.
