Programing issues

Tinkerworksgarage

Ok I have been working on this printer for awhile. I have gotten all my wiring done and have tried programming numerous times. I can not get xyz to home correctly. i can not get bltouch to work. seriously pulling my hair out. I have been working and trying to figure out programming for over a month now. I guess its time to ask for help as i am just not getting it.
I have a tronxy x5sa that has been converted to duet 2 wifi. I have 3.3 on board. I have Bltouch.
i need to get this thing operational. Any and all help would be much appreciated.

@tinkerworksgarage you came to the right place

Post your config.g and homing files so we can see what stage you've got to. Also post the response to M115 to confirm your firmware version (just in case anything went wrong here).

Probably best to start at the top and work through things. Start with basic motion and homing x and y. What exactly happens when you hit homex or homey?

Edit: Pro tip. If you post your files by copy pasting the contents and using the </> code snippet tool (two down from bullet points), it makes it a bit easier to read

FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.3 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2021-06-15 21:45:03

When I home x or y bed moves up a little then x or y move backwards a little. Bed then moves back down and it stops. If i home z it moves down and does not stop.

I have used the rrf config tool. something doesnt seem right. I had a config update lose connection part way thru and had to reprogram board. I had x and y working correct (after lost update) then it just started this.

@tinkerworksgarage okay. When you say x and y move backwards a little, do you mean they both move away from the endstops (by about 5mm)? If so then your x and y directions are correct.

Your z direction is incorrect (the bed moves up when it should move down) so change

M569 P2 S1 ; physical drive 2 goes forwards

To

M569 P2 S0 ; physical drive 2 goes backwards

Next onto your homing. It should like your x and y endstops are already triggered so as soon as it starts the homing move, it thinks it's at the endstops

G1 H1 X-235 F1800 ; move quickly to X axis endstop and stop there (first pass)

This is the long homing move to xmin (where your endstop is). It doesn't do this move because the endstop is already triggered.

So you need to test your endstops and reconfigure them. Send M119 and it will report the current state of the endstops. Try this with and without the endstops pressed.

My guess is you will need to invert both x and y endstops by adding an exclamation mark to the pin name. E.g. change

M574 X1 S1 P"xstop" ; configure switch-type (e.g. microswitch) endstop for low end on X via pin xstop

To

M574 X1 S1 P"!xstop" ; configure switch-type (e.g. microswitch) endstop for low end on X via pin xstop and invert

Let us know how you get on from there

Not sure if you've found all the Duet documentation but all this should be covered there. A couple of good ones to read through are:
https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter
https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter
https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+3:+Commissioning/39 (granted this one is a different printer/board but the steps to take are all the same)

Edit: corrected my mistake on M569. Thanks @jay_s_uk

S2 isn't valid. It's S0 or S1

you also don't have a servo defined so the BLTouch will never deploy

The BLTouch should be setup with M558 P9, and the position in reference to the nozzle of X and Y must be defined in G31 (otherwise the mesh compensation is at a wrong place later), please check both in
https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_BLTouch
If you are in front of the printer, a positive X means the BLTouch is right to the nozzle, and a positive Y means it is behind the nozzle, values being mm.

Thank you all for the help!!!!!!!!!!! Finally getting it figured out some. Next issue is when homing x the y will hit end and just keep trying to move. same when home y the x will hit end and just keep trying to move. How do I cure it so when homing either the other will move relatively so not to crash?

Tinkerworksgarage

I am also in testing so not everything is mounted or mounted permanent like hotend or bltouch. That is
why I had no values as those will be entered later.

Would to this work to hold position for y as x moves to home. same would be done for x as y homes?

I don't quite understand why your Y axis would move when you command a move in the X axis.

Can you try entering G1 X moves one way and the other and verify that the Y axis does not move at all? It shouldn't.

G91               ; relative positioning
G1 X20 F1800
G1 X-20 F1800

Entering these should move ONLY the X-axis right 20mm and then left 20mm

Ok so tried this and y stays still as x homes but x hits endstop switch and keeps trying to move more.

Tinkerworksgarage

@alankilian
It will not let me as axis is not homed already.

Tinkerworksgarage

I don't get it. I had x working decent but y would still move some. Also had y moving decent but x would still move some. Even had Y staying still and was able to home x. then all of a sudden it all went haywire again. I even did M669 K1 to make sure was still in corexy mode. Back to moving and crashing

alankilian

@tinkerworksgarage

You can do M564 to allow movements without homing.

Please post your complete config.g

The one your posted earlier has your machine configured in Cartesian mode which would cause all these problems.

Ok here is complete config.g file with what I have setup right now. I believe it is setup for corexy but am not sure how to check to see. I also believe that this could be one of the main problems (possibly could be reverting back to cartesian on its own) If it is reverting back how do I get it to stay in corexy.

@tinkerworksgarage said in Programing issues:

I even did M669 K1 to make sure was still in corexy mode

That is not enough to insure that XY motions are correct.

Did you read the docs on how to get your steppers configured and wired correctly?

You must have Cartesian checked in the Reprap Configuration Tool.
Your config.g is NOT set for corexy. If it was it would have an M669 K1 near the top.

HERE is the document that tells you step-by-step how to configure it and get the motor-direction descriptions right. (Thanks @fcwilt)
