Did you use M307 H7 A-1 C-1 D-1 to disable heater 7? Until you do that, you can't use logical pin 7 in M280 or M42 commands.
Perfect, i did it and now the g30 command works.
I encounter another issue now, when i start auto delta calibration the bl touch isnt triggering because my machine wont move all the way to the plate when probing.
the only probing point it actually reaches the plate to trigger the bltouch is on the center of the plate, for the last probing movement.
Temporarily increase the dive height (H parameter in M558) to 30 or 50, until you have calibrated the machine and updated your M665 parameters.
You can already move the axes directly using the encoder in firmware 2.02RC5, as I expect you know already. The movement increment is 0.02mm for Z and 0.1mm for other axes. How would it be if I make the increment 1mm on all axes after a long press instead of a short one?
I was looking at the maximum power on page two for current estimates.
In any case, I just made a duplicate board and connected it to my test printer with a 24 AWG, 3ft ethernet cable and it worked just fine. Literally just plugged it in and it worked. I have a 7ft cable for my main printer coming in on Friday - I expect it to solve the problem.
All ethernet cables are NOT created equally...
@skyraccoon said in Heater stops when Cooling Fan starts:
Yes... that's it .
So I see two solutions here.
1] Put A silicon around the head
2] Turn the head so the thermistor is not facing the air fan flow.
Even better is to adjust the fan duct to blow at the print below the nozzle, not at the heater.
Thank you guys for the comments and your ideas.
For oozing before Z calibration I am planning to Install brush like in Makerbot. But I don't know how effective will it be.
@deckingman I will check your page as I would also like to use mechanical switch.
I will update as soon as I have modified my printer.
@frank26080115 said in Unable to find UART pins for Prusa MMU v2.0:
Is the support for the MMU v2.0 on the roadmap for you guys at all? How welcome would code contributions for MMU integration be? Is there anything you would like me to avoid doing?
It's not on our roadmap, although that could change if enough users request it.
It might make more sense to use the Duet to drive the motors etc. in the MMU directly. Alternatively, another user has made a device similar to the MMU, see https://forum.duet3d.com/topic/6346/multi-material-filament-feeder-repurpose-e1-stepper-driver.
it does appear to be the case that its ~80mA per RGBW section (20mA*4), with 20 sections per meter for this product.
Would the amps drawn be linear w/ the PWM range i.e. full 20mA per section at S255, but 2mA at S25.5?
Assuming you're using firmware retraction you can use G10 and G11 to retract.
G1 X0 Y0 F6000 to move the head to home. The faster you can do this, the better for oozing. Trigger your photo. Unretract. Then I would think that because it's absolute coordinates it should move to the next layer height and continue. Actually, if you insert your code AFTER the layer height move, and you have retract on layer change, it will already handle the retraction for you, and give you some clearance from the printed part for the travel move out of the way.
@timidtinkerer the USB socket is device only and USB dongles need to work with a USB host. The easiest way ti sot get a Ethernet-Wifi bridge. there are lots of them out there and infact thats how we made the old first generation Duets wireless, see this older blog post about using a TP-Link
@t3p3tony said in An extruder to turn a spool:
@deckingman nice write up. With 5 extrucers you are always coming up against stuff that most other people don't have to worry about (like changing the middle spool of 3!)
Thanks Tony. And exactly so. For most people changing a reel of filament is relatively quick and painless job. Changing the middle spool of 3 is one thing but when I swap from say a Diamond 3 colour to a Diamond 5 colour, I have to unload 3 spools, then load up 5 spools so it's a bit of major operation. Less painful than it used to be now though.....
Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
