@mloidl said in BLTouch Trigger not working: A blink LED normally indicates an error. Have you tried removing the I1 from the M280 command. On my BL-Touch i had to add I1 because it was blinking without it. Maybe that's different for the 3DTouch. Yes, I tried all these combinations: M280 P3 S10 I1 M280 P3 S10 M280 P3 S90 I1 M280 P3 S90 M280 P3 S160 I1 M280 P3 S160 The result is always the same: blinking led.

Whenever I start a print, I get stall warnings during the homing process. If I start the homing by clicking on the button in DWC, I do not get these warnings.

increase the H param on your M558 line (Temporarily) to say H30 and try again sounds like you have your Homed hight set a little high in your M665 line and that is what is causing the initial head crash. HTH Doug

Thanks for the info and diagram, @coffee! In terms of connecting the steppers in series, is there an advantage to hooking them up like you did as opposed to this setup:

All - I've made the two changes as instructed: M558 P1 X0 Y0 Z0 H30 F1000 T5000 G1 S1 X400 Y400 Z400 Progress so far: The auto probe calibration works with the Z probe except for the far XY edge where it drags along the bed (the IR sensor is positioned off the side of the bed - it sees nothing so the nozzle eats the bed). This is amazing progress, though. Because reterminating the IR Z probe connectors got it to work (in theory). However, it looks like the printer still thinks that Z=5.3 is the same thing as Z=0. When I try to print something like the XYZ calibration cube, the nozzle drops down to Z5.30 (5.3mm above the bed) and spews filament onto the bed. Recalibrating (and entering M500 to save settings) doesn't resolve the issue. What might be causing this stubborn behavior in the printer?

Can't do two Duex5s, but can do an extra 2 external steppers through a connector on the Duet Wifi/Ethernet, bringing the total stepper drivers to 12. 3 for X/Y/Z, 3 for multimaterial, would leave 6 for your tool changing.

I did try the schematic I have indicated over a month ago and it doesn't really work! The VFD is a 1.5kW Huanyang and it works as expected, just that the board is not capable of producing the voltage, nor to change it in a rather linear manner. Amazon has several such boards readily available and for very low prices (so low that I regret spending half a day trying to sort out the problem!). I will return with comments when the one that I have ordered arrives.

@enix you can access the I2C bus pins from the Duex expansion header as well: https://duet3d.dozuki.com/Wiki/Duex_wiring_diagrams

@wilriker That is interesting. Maybe I just never tried retraction, nor paid attention to the retraction becoming enabled at any temp because I was looking to extrude. As far as it becoming configurable, I'd definitely like to see that. I know Marlin FW uses M302 Pxx Sxx with Pxx being the flag on/off and Sxx being the temp setting. I have used it to change the temp on a couple of my machines before for the aforementioned reasons. Just food for thought...

@danal Hi Danal. Feel like I know you from all the other Anypubic threads I’ve opened the power adapter up and going to use insulated crimp ring connector to the power supply, and the ferrules that came with the kit. Decided to do it properly, and ordered 12awg wire for the job as well. Thanks!

@sjason1377 Oh, and regarding how you did regarding being level: nearly 0.4mm difference between highest and lowest point is a lot when you look at the fact that many people print at 0.2mm layer height. But this could also be defined by outliers solely so (without fully understanding the meaning of RMS error) this is a little hard to tell. You might want to upload the image of the height map as displayed in DWC.

@adras Just to be nitpicking: in your diagram you wired the weaker 10A PSU to the bed instead of how you described it in your first post where the more powerful 12A PSU was powering the heater. Did you change that intentionally or did it just slip?

When I tried heater 3 the first time I was still using I1 instead of I0, so I tested this again and I was able to get it working with heater 3 and PWM1 I tried heater 7 and PWM5 again, that still isn't working. I may test some of the other configurations just to see if this is isolated to that connector, but I don't have any plans to use heater 3, so I might just call it good as long as everything is working. Thanks!

screen came with the 4 pin cable... I tired that but it didn't work - the screen looks a bit like it's crashed - I'll try to get a photo later on print head still keeps pausing when it moves between different areas I don't know if it's relevant at all but it seams to over retract when it finishes printing too, not always but a couple of times I've had to push the abs back in because it's so far out the gear doesn't touch it I'm a bit lost with the pausing thing (p.s. I tried with a couple of different files to make sure it wasn't me/cura causing it)

@danal Thanks so much for this, going to get cracking once the kids are in bed. I actually just retrieved the rod length stickers out of the bin after you mentioned it included the ball measurements too. Thanks for that! I'm lucky I have a second printer as I've used it to print off the print cooling fan shroud and also a 40mm hot end fan replacement after I put my thumb through the e3d provided stock fan and fortunately had a 40mm fan spare. Whoops! Thanks again, I'm sure I'll be back

@dc42 said in Heaterfault due to temp drop: The nature of the temperature graph suggests to me that there is a problem in the thermistor wiring. The fault came up again today, so I went trough the usual procedure of resetting and turning the heater on again. Only this time I noticed bumping my printer actually causes a 10-20°C temperature fluctuation, producing a temperature graph I not comfortable posting here. Sadly I was not able to make it fluctuate just by fiddling and wiggling with the thermistor wire/connection.

I found the mistake! After doing some tests with all the possible options, i found out that only when the command was Xnnn with Tool 3 selected did the axis not move. When it was Wnnn it did move, either it it was absolut or relative, G0 or G1, heated or not heated. That meant the X axis of tool 3 was not correctly mapped. And voila: "M563 P3 D3 H1 X6 F3", where the 6 had to be a 5. Thank you very much for your tips and your help!
