@mrsyfo said in Expansion board with 5v drivers:
i think i have figured it out, the pwm pins on the breakboard of heater 7 are equivalent to PWM5 so im thinking that the correct code for me is the next one:
M574 Z1 S2 ; Set endstops controlled by probe
M307 H7 A-1 C-1 D-1 ; Disable heater on PWM channel for BLTouch
M558 P9 H5 F120 T6000 ; Set Z probe type to bltouch and the dive height + speeds
G31 P500 X0 Y0 Z2.5 ; Set Z probe trigger value, offset and trigger height
M557 X15:11 Y15:195 S20 ; Define mesh grid
am i right?
Yes you are right, and you need P7 in the M280 commands the deploy and retract the pin.
Like mentioning to add in "M280 Px S150" if running on 3.3V for added safety, maybe mention adding a pullup resistor between Z-probe in and 3.3V on the Z-probe connector. Just generally make it more readable. I don't know how many times i read it back and twards before getting it (might be because i'm not a native English speaker to ofc.) But it could be made much easier to read for a newb.
@makerdise said in IR Probe broken?:
@dc42 @pedrinid - Ok, we will send out a new as a replacement, it doesn't make sense to return the old as the shipping costs are to high.
I agree. Thanks for your support.
@lb said in PT100-board wishlist EMI - component maybe...:
Is that already on the PT100-1.1-Version or from a new version on? (And will duet3 use also this daughterboard-eco-system?)
The PT100 PCB revision 1.1a has the pads for the extra capacitors, however they were not fitted in the first production run using that PCB because we hadn't completed tests with the new capacitors fitted.
The prototype Duet 3 main and expansion boards support the same PT100 and thermocouple daughter boards, and that's unlikely to change for production.
I was able to solve this issue by upgrading to a 2.03 firmware release. While reading another thread here on flying extruders from earlier this year, I failed to realize that the supporting firmware was much newer than I though. So, all is well!
@caveman said in Connect pinda probe to Duet Maestro?:
So i figured why not use it on my Anycubic Linear Plus.
a delta really wants the probe to be the nozzle. i tried a inductive probe on mine but could not get good results.
@synapsis said in IR Probe False Reading:
Ok still not working , Question is why do I have a reading of 29 to 33 when the bed is even a 150mm down.
Shouldn't it be zero or over 1000 when very far away from the bed?
Yes. A reading of around 30 suggests to me that you have a bad connection between the IR sensor and the Duet.
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
@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.
