Print head crashing into X/Y axis!
-
Hello all,
I've had something of a nightmare getting my printer going of late; it's a coreXY Fusion3 F400-S, which came with an 0.8.5 when I got it and the firmware wasn't straight-up DuetFirmware -it was edited of some sorts. It was also old, so far as I can tell (1.17 was my most recent.)
I've changed it due to faults with the board and got a Wifi - also changed out the PanelDue controller from a v1.1 to a v3 - hadn't intended to, but it didn't play nice with the firmware when I loaded it. It was Fusion3's again. So then, I thought sod it - and got rid of the Fusion3 firmware and loaded up 2.02 (had more issues...) then upped it to 2.03 where it's at now along with web controller 1.22.6.
Have had so many issues with my printer I can't begin - but always with mechanically stuff... never with the board/ code etc. So, all that side of it is a learning curve to me at the moment.
I'ver spent the day swapping out the 0.8.5 with the wifi (after getting connected to DWC this morning
), then when I ran the axis homing earlier - it did the z, but gave me "g0/g1 insufficient axes homed" for x & y. I spent quite a while trying to understand what's going on with the gcode and editing my homely, home, homey, homez.g files but when I've just tried to get it going it's still not playing nicely and despite searching and looking over as much info as I can, I can't see why.I currently have:

When I run the home all - the Z works a charm. I then moved the bed up 50mm and ran the home Z - lovely.
I ran the home X and it moved in the Y - didn't stop at the limit and made a gut-wrenching loud noise as it continued to (try to) move through a solid object (the frame).
I tried the home Y and it moves in the X - so I stopped it before it ran aground like the home X command.
Am I missing something obvious?

It may help to go through this: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter
Especially the part where you test individual motor direction in the Movement section. I think you've probably got a direction reversed. This makes sense I think since there was a bug fix between your old firmware and the more recent 1.20 version.
Once that's solved, everything else should work...
Growing pains when going from a very old firmware to a very recent firmware. I think you're on your way though.
-
As @Phaedrux says, you will need to reverse one of the motor directions. From memory, I think it is the Y motor, and you need to change S0 to S1 or vice versa in the M569 P1 command in config.g.
-
As others have said, there was a change in the firmware which meant that CoreXY users had to alter the motor direction for one of the motors. I believe it was the beta motor (normally connect to "Y" but the safest thing is to run through the motor testing in the link that @Phaedrux posted.

Thanks all.
@Phaedrux: I had a read over the link you sent over earlier as best I could whilst at work. Home now and trying to edit the config.g - it has M667 S1 set, so that's now commented out and I have M669 K1 in it's place.
Fingers crossed - will keep you all informed on my progress!

Currently either will work, but M667 K1 is the correct way going forward.

Cool, thanks. I'll keep that from now on.
Just now managed to get it running and I'm very pleased!

Indeed it was. Presumably, the more au fait around here could write it out in 10 minutes but getting used to the code is time consuming wrapping my head around it.
