@Phaedrux @dc42 @T3P3Tony

Hi all, It turned out to be the end-stops micro switches causing the board to lose connection. I read up on the on "Connecting endstop switches - What might go wrong" and then I corrected the wiring and all is good with that.

Now I need to figure out what is causing my X and Y axis make a continuous "ta ta ta..." sound (like a machine gun), while jumping back about several mm then to a stop when it triggers the end-stop; only when I Home All and individually home the Y axis, but the X axis behaves normal in when I home individually.

Any ideas?

Thank you all for your help.

Jumping solved! Did a new RepRap Config at RRF, there may have been a error in my part on the first RRF config.

Please closed this as solved.

Thanks.

@Phaedrux Sorry for getting back late, I was out on a business trip.

For the Duet2 WIFI, the current was set to 1A and ran without issues, but I understand it has different drivers and beside the fact it's older, nonetheless it worked.

No issues with other axis.

I changed the motor drive current to all the axis to 80% of motor mA specs, but that didn't change the behavior, as it the extruder motor still shuddered when commanded to extrude.

Although after enabling StealthChop it is now extruding. To verify, I have power-cycled the printer multiple times and now when I run an M302 P1 it extrudes and printed a 20mm cube without issues.

Issue RESOLVED!

Thank you for the support!

@gloomyandy Hi.

I just solved the issue. I noticed in Object Model that the Y endstop was not showing "highEnd" and "type" it was for the X, but it was triggering, but not home as mentioned. So I switched over to another io, io5 to io2 and that solved it!

One more thing, I switched over to Normally Closed.

Hi all.

I decommissioned a delta and repurposed the Mini 5 on an old TAZ 4, which ran solid with the Maestro board, but I thought I'd give it an upgrade. I feel I'm 99% there, but the y axis has me frustrated.

When I command a "homeall", I notice an odd behavior with the y axis, it starts at the same time as x, but then the y stalls, then tries to move again with hesitation, only after the x has finished it's homing procedure. The y restarts slowly, then accelerates hitting the minimum limit hard (I e-stop it here).

I have tried several things, like reversing the direction of y and changing the endstop to high end, no success. Changed the drive assignment physically and in the config to match, same results. M119, show that the endstops are getting triggered when I actuate them by hand. Nonetheless, x and z axis home fine.

Than you!

@o_lampe Yes, I know that. I had the motor removed from the extruder gear housing. What I meant is that I'm using M302 P1 and commanding "Extrude" from the GUI to monitor movement for testing.

@Phaedrux Sorry for getting back late, I was out on a business trip.

For the Duet2 WIFI, the current was set to 1A and ran without issues, but I understand it has different drivers and beside the fact it's older, nonetheless it worked.

No issues with other axis.

I changed the motor drive current to all the axis to 80% of motor mA specs, but that didn't change the behavior, as it the extruder motor still shuddered when commanded to extrude.

Although after enabling StealthChop it is now extruding. To verify, I have power-cycled the printer multiple times and now when I run an M302 P1 it extrudes and printed a 20mm cube without issues.

Issue RESOLVED!

Thank you for the support!

@Phaedrux okay, I didn't want to higher than 1mA risking damage to the driver, ignorance mainly, but I will try going higher as you suggested once I get a chance.

Why does the driver drive the motor in reverse (retract) with the mA current settings?

Thank you.

@OwenD I have already done that. I've explained that on my initial post.

@Phaedrux

What are the specs of the motor? Wantai - 42BYGHW609P1-X10, 1.8 degree Stepper, 1.7A

Have you tried a different motor? Yes. Same issue.

Have you tried the motor out of the extruder mechanism? Yes, I removed motor from the gear extruder housing, it's how I ran M302 P1.

Is there something mechanically restricting it? No. As I mentioned, I can change the mA values in the Config and restart the config, although I have to repeat the process until I can get it to work.

It sounds like either a problem with the motor or the extruder mechanism. Not likely, If I reinstall the Deut2 WiFi it works perfect.

@o_lampe , Hi. Happy New Year!

Okay, I just tried the M302, allow for cold extrude.

Same results, NO stepper motor movement when commanding to extruding, only movement is when retracting.

Prior to the M302, I was reaching the temperature target, no issue with temp.

Thank you for your support.

After retiring my Duet2 WIFI board and replacing it with a new Mini 5, the board is not driving the extruder stepper motor when trying to extrude. I have verified continuity from the stepper motor connector to the board connector and found no issues and motor phases are correct too. I have switched from stepper driver 3 to 4, and making the necessary changes in the config to reflect driver change and the same issue. Same behavior is encountered, neither stepper driver drives the extruder motor in the direction to extrude, only functions in retract.
I have also changed firmware, from 3.4.4 to 3.4.5, and back down to 3.4.2, no change in function. The only success I have had is changing the value of the mA settings in config. When I changed the value from the default of 800 mA to 1000 mA the printer will function as long as I don't shut the power off. If power-cycled the printer it will cease to function and I will have to play with the config's driving mA until I can get the stepper drive to function again. If I change out the board to my old Duet2 WIFI (switched to old duet config), they're no issues. But when I re-install the Mini 5 again to once again verify operation, the same issue. The reason I switched from the Duet2 board is I prefer LAN to operate all my devices.

When I command to extrude from the UI, and place my fingers on the motor's shaft, it shudders. Although when I select retract, the motor will spin.

What I'm missing here? I'm I missing a line in the config the Duet3's need? Again, no issue with the Duet2 WIFI.
