New experimental firmware 1.19beta11
-
Hi Ian,
The X and Y motor assignment changed at beta 9. However, it's just not possible that the head moves in the wrong directions in exactly the same way when you swap them (either in the wiring or in the M584 drive assignments). Please check again what they are doing. I think you will find that one of them is moving the wrong axis in the negative direction, not positive. In which case, you need to use M569 to reverse one of the motor directions.
-
David,
You're right. There is a slight difference when I check carefully.
X-10 std wiring = Y-10, reversed wiring = Y+10
Y-10 std wiring = X-10, reversed wiring = X-10 (the same)
X+10 std wiring = Y+10, reversed wiring = Y-10
Y+10 std wiring = X+10, reversed wiring = X+10 (also the same).I'll play around with motor directions to see if I can fix it.
-
I've tried every combination of direction. The best I can get is that X moves as it should but Y moves positive instead of negative. It's too late and I'm too tired. I''ll try gain tomorrow after I've slept on it.
-
You need to use what you are calling reversed wiring.
-
OK. So with "reversed wiring", that is to say the X motors were connected to drives 0 and 3 and the Y were connected to 1 and 4 so now with "reversed wiring" X motors are now connected to drives 1 and 4 and Y motors are connected to drives 0 and 3.
I've tried all 4 combinations of motor direction and here is what I get.
P0 S1, P1 S0, P3 S1, and P4 S0.

Support 2 additional external drivers connected to the CONN_LCD socket
Where can I find more information about this feature?

Hi Ian,
Please do the individual X and Y motor tests (G1 S2 commands) described at https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_CoreXY_printer#Movement_section. I may have been wrong about swapping the X and Y motors, it may be that you just needed to reverse the direction of the Y motor,

Hi David,
Yes it's looking like we don't need swap the wires. With them swapped from their original position when I do G91 then G1 S2 X10 F3000 I get +X -Y (plus X minus Y) movement. G1 S2 Y10 F3000 gives me -X -Y (minus X and Y).
I'll swap the wires back to their original positions and play around with motor directions again.
Ian

Yes that's fixed it. Wiring back to how it was. P0 and P3 set to S0 which is original. P1 and P4 set to S0 instead of the original S1 and now all movement in X and Y is as expected. Thank God I'm not actually losing my mind which is the conclusion that I was rapidly heading towards
So in summary, wiring needs to stay the same but Y motor direction needs to be reversed.
Wonder why no one else has picked up on this?
-
Thanks Ian, I'll correct the release notes. The reason I thought they needed to be swapped is because so many CoreXY users reported mirrored axes, which made me think it was caused by RRF not following the standard convention. Now I know that is wasn't.
-
Next problem. What's happened with G30? That's how I've always homed my Z axis - don't do any sort of flatness or level compensation. So my home Z is simply move up 5mm, move the centre of the bed, heat the hot end slightly to 140 to soften any blobs, then do G30, move back up 5mm and turn off the heater. Now when I try it, crazy things happen and it's all to do with G30.
So if I home X and Y, move the head to the centre of the bed then do G30, X and Y travel towards zero (but don't stop when they hit a switch, and Z simultaneously moves down (negative) seemingly forever but I have top hit emergency stop.
Edit. Oh and after an emergency stop, DWC asks to reset the firmware, I say yes, but the machine remains halted and I have to cycle the power to clear it.
-
Read the upgrade notes for beta 10.
-
Yes, found it. Deleted deploy probe and retract probe files and that has fixed it. Too much happening at once what with my fairly major machine upgrades as well as trying to keep abreast of all the firmware changes. Starting to feel my age….........

I get alot of ajax timeout errors. Feels like its every other minute…
To get it to work again I have to M552 S0 and M552 S1

The 404 error trying to load oem.json is normal, but the other errors are not. If the wifi module disconnects from the access point then it should try to reconnect automatically, so DWC should be able to reconnect after 20 seconds or so without having to use M552. I'll test the auto reconnect functionality in WiFiServer beta 10.
Have you tried increasing the number of retries configured in DWC? The default is 1.
-
Retry count was 1, I increased it to 2. Doubt it will help. the duet stops responding to ping and will not start responding in the 20 sec you stated. I get nothing on the panel duo console until I do the M552 S0.

Hello david,
Today I have free time I have tried the emergency stop again. It seems to only affect when doing a G29. If an emergency stop is made while running a G29, the printer stops and the firmware restarts, but it is still in the "HALTED" state and the power must be removed to restore its state.
I repeat, it just seems to happen if an emergency stop is made while running a G29
a greeting

Thanks, I'll see if I can reproduce that.

So after updating to this firmware, my board as become completely unresponsive over night. initially it worked, but the web server kept crashing, as of this morning, the board, can not connect via wifi, or pointerface. As well as after to trying to attempt the Fallback procedure #3 I cant get the board to connect to SAM-BA.
I already followed the directions to a T
