Issues with Homing Delta on RRF3

[aerouta]

@JoergS5 The videos show that the first axis to reach the endstop begins the jitter. I tested each axis one at a time and confirmed what is seen on the video. Attempting to home one axis begins the jitter on that axis.

Is there any changes from board V1.01 to V1.04 that could cause this? This was another change that was made. My v1.01 board developed an intermintate failure that resulted in both thermocouples to fault. I then purchased the .04 board and upgraded to RRF3. This is my first attempt to use the new .04 board.

[JoergS5]

@aerouta I have also a 1.04 board.

The release history is here: https://duet3d.dozuki.com/Wiki/Hardware_Overview#Section_PCB_revision_history
I cannot see something related to your problem, but check also.

My last idea is that you have an endstop type which now needs the ! in the syntax, according to https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_RepRapFirmware_Num_3
M574 X2 S1 P"!xstop"
etc.
Do you have your old config, did it use M574 S0? This would be S1 with ! now.

You can also recheck the RRF3 upgrade checklist in https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview

@JoergS5 @dc42
Old config...

M574 X2 Y2 Z2 S1			; set endstop configuration (all endstops at high end, active high)

[Phaedrux]

@aerouta said in Issues with Homing Delta on RRF3:

Error: in file macro line 88 column 10: M92: array too long, max length = 1

Does this error still show up when you send M98 Pconfig.g?

Can you verify your firmware version by sending M115. It should be 3.1.1

And please share your newly changed config.g

Can you test your endstops by hand and watch the DWC machine page for the endstops. When looking at the front of the printer, the X tower is on the left, the Y tower is on the right and the Z tower is at the back. +X movement is to the right and +Y movement is towards the rear. Verify that when you press the X tower endstop the X endstop triggers, etc.

I wonder if maybe an endstop plug is swapped or not working.

[aerouta]

@Phaedrux I conducted the test you suggested. Endstop index 0, 1, 2 triggered on towers X, Y, Z respectively.

I no longer get the M92 error during the M98 command and my firmware version is confirmed to be 3.1.1

Can you alter your M350 and M92 lines to include the Z and E axis respectively? And lets include an explicit M584 to map the drivers to their respective axis.

You have:

M350 X16 Y16 E16 I1    				; Set 16x microstepping with interpolation
M92 X106.667 Y106.667 Z106.667		; Set axis steps/mm

Change it to:

M584 X0 Y1 Z2 E3 ; Driver 0 controls the X motor, 1 controls Y, 2 controls Z motor, 3 control E motor
M350 X16 Y16 Z16 E16 I1    				; Set 16x microstepping with interpolation
M92 X106.667 Y106.667 Z106.667 E470		; Set axis steps/mm

Then you can remove the M92 E470 that occurs lower down in the config.

Also, I'm not sure it matters, but when comparing to a fresh delta config from the web tool, the M665 delta commands are placed higher in the config.g file near the top before all the drive commands.

Here it is for comparison:

@aerouta config.g looks okay, except there's an extra M92 at line 82, but as it's the same as the earlier one, it shouldn't cause a problem.

Did you disconnect any motors or endstops, or rewire the machine? Because it really sound like two of the endstops (or motors) have been swapped, so are not related to the correct axis. That's why 2 of the 3 axes reach the endstop; one correctly hits the endstop and stops, one hits the endstop and stops the third, but continues to move, as the third hasn't hit the switch that would stop the second, until you press it with your finger.

Move each motor individually so you know which tower is which, by sending G1 H2 X10 F100 (which will move just the X axis). Then press the switch on that tower, and check it activates the X endstop (send M119 to check status or check in DWC > Machine-Specific > Endstops). Repeat for the Y and Z towers.

[aerouta]

@droftarts Yes, I did switch from a 1.01 to a 1.04 board. I will recheck all my motor and endstop connections.

[aerouta]

@droftarts the motor connects were switched! good catch!
