  Hi there Winged Donkey.. This is my first post so please bear with me. I’ve just upgraded to the DUET2 WiFi board from a cnc vpro2 My old vpro2 board ran a 15w PWM laser ok. M3 M5 S255 etc. I’m looking into following your lead / research to get my PWM laser to work. Did you solve all of your issues in getting you laser to work? Has your PCB worked as designed? If you still have any of the spare boards, would you be willing to post a couple to me in the UK? I’ll cover the cost if you can help Best regards Phil T

  Interesting pump. Looks like the 6 litre-per-minute brushless version with pwm and tachometer. At $9.50 each, I may have to grab a few to play with.

  Bltouch Error: Z probe was not triggered during probing move

  @doerofthings said in Bltouch Error: Z probe was not triggered during probing move: G92 Z11 ; set Z to axis minimum (you may want to adjust this) Remove this from your homeall.g and homez.g. You definitely don't want to force the z height after you've used the probe to find the real height with G30. This explains why changing the offset had no effect, because you are overriding it. I have a feeling that your bltouch may be mounted a bit too high as well. It should be mounted so that the base of the probe body is 8mm above the nozzle tip. When installed correctly, the trigger height will be around 2mm. Once you've done that, recheck your trigger height with this procedure: https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe#Section_Calibrate_the_Z_probe_trigger_height Then you can rerun your G29 if you want to use it.

  @shaneh, you are right about M92 and M350. However, M18 and M84 can still be used to turn off current to external drivers, if you have connected the Enable signals to them.

  @wyvern said in Updated tangle-free spool holder: Cool, just a thought, for a cheaper and more accessible part, you could pause close to the end of the print and put in steel or lead shot. I thought about doing that- just fill the printed roller up. You'd want to include resin or wax to keep the stuff from moving around, I think. Then Tom offered to turn a steel roller on the lathe so ...

  @dc42 said in Laser Filament Monitor 'SW' PCB Pads - Unsolved: @snowcrash said in Laser Filament Monitor 'SW' PCB Pads - Unsolved: Ok, so... was my original understanding correct? that is, the voltage reading between the 2 pads (High/Low) serves as an indicator for filament present/not-present? Our intention is that if you want to add a filament presence switch, you add a switch that shorts those 2 pads together when filament is present. To make it easier for us (or anyone else) to prototype new functionality. In what why exactly? could you please give an example? No, because we haven't used them yet. Ok, thanks

  The control wire can go to various pins, you can choose any of the additional heater outputs on the expansion connector. Our standard instructions use pin 8, see https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Duet_2_WiFi_Ethernet_without_a_Duex_2_or_Duex_5_expansion_board.

  I believe I was experiencing a similar issue. I found that this suggestion corrected my problem: "If you connect your bltouch and when auto homing the sensor doesn’t register & the z axis keeps dropping pressing into your bed, turn your printer off, disconnect the power and invert the black and white connectors in the z limit switch header (put black where white was, put white where black was)." I pulled this from this from The complete BLTouch/3DTouch guide for Creality printers (CR-10/s,Ender 2,Ender 3) for Auto Bed Leveling by dannyw281. I hope this helps you out. I know it was a great relief to me. Granted this was on another brand of printer, but when it comes to the behavior you are experiencing I don't think the wires care what brand the printer is.

  Ok i will update it. Shit i think you are right. I can see that i have an M584 call in there... but if i delete this, then my second z-axe dos not work.... any idea? Your help is very appreciated Here are my z-axis homing code: ; homez.g ; called to home the Z axis ; ; Lift Z relatively to current position G91 G1 Z2 F6000 S2 ; split Z motor control to Z and U ; for it to work we have to show U (param P4) in the UI M584 Z2 U3 P4 ; Move Z and U down until the switches triggers G1 S1 Z-205 U-205 F1000 S2 ; back to combined axes and hidden U M584 Z2:3 P3 ; Back to absolute positioning G90 ; Tell the firmware where we are G92 Z0 ; lift Z after probing G91 G1 Z3 F1000 S2 G90 ;--------------- repeat slowly---------- ; split Z motor control to Z and U ; for it to work we have to show U (param P4) in the UI M584 Z2 U3 P4 ; Move Z and U down until the switches triggers G1 S1 Z-205 U-205 F50 S2 ; back to combined axes and hidden U M584 Z2:3 P3 ; Back to absolute positioning G90 ; Tell the firmware where we are G92 Z0 ; lift Z after probing G91 G1 Z10 F1000 S2 G90
