Re: Converting MAX v3 to ATX PSU

The disadvantages of ATX PSUs are that you generally need to put a dummy load on the 5V output, the output voltage is not adjustable, it is likely to be a little less than 12V, and unless you buy a good brand name PSU then it is likely to be not well regulated. All of which means that you may be sho...

To get a more accurate reading from the thermocouple, feed it into the hot end through a short Bowden tube instead of filament.

Re: adarcher's build/troubleshooting

Yup, but something else is different in the 1.21 firmware because without changing from stock anything, the XYZ motors create that highpitch noise and don't move--that's what I was talking about, the extruder is what reminded me of what could be the issue. The culprit was the "G0 Z5 F30000;&qu...

Re: Duet Tuning.

https://www.repetier.com/dead-time-control/ OK, at present this just seems to be an issue on warmup not when the hotend is up to temperature. There is no M307 in the default configuration file for H1 In that case I suggest you run M303 heater tuning, and transfer the results to a M307 command in co...

Re: Duet Ethernet connectivity problems

We get very few issues with connectivity on the Duet Ethernet. Have you tried a different Ethernet cable, and a different port on your router or switch? Are you certain that the IP address you assigned to the Duet isn't also being used by another device? If you've already checked those things then p...

Re: Duet Ethernet connectivity problems

That ending code looks ok except that on some deltas, turning off the motors with M84 may allow the effector to drop so that the still-hot nozzle melts into the print. I suggest you leave out the M84. The motor current will be reduced to the idle value after 30 seconds of no movement anyway.

Re: Duet Ethernet connectivity problems

Have you tried assigning the Duet a static IP address in the M552 command? There were some potential issues with the DHCP client when the lease expired, and although I believe these are fixed in firmware 1.21 it's hard to be sure.

You can't print an STL file directly, you need to slice it first.

As you are using USB, see https://duet3d.dozuki.com/Wiki/USB_ground_loops. Also do not use Repetier host unless you know how to stop it enabling debug.

Shorts between hot end wiring and thermistors are surprisingly common, which is why we designed the Duet WiFi and Duet Ethernet to withstand them.

Re: scaling in X and Y as it gets taller (z direction travel)

Is your tower spacing exactly the same at top and bottom? A larger spacing at the top would cause shrinkage with increasing height. If it's not that, maybe it's something to do with heat rising from the bed.

Re: Enable strain gauge Z probe?

DC.. to me the collision detection would be a real plus. Collision detection on Delta printers is difficult for two reasons. One is that delta printers are usually designed to print fast. That means that low inductance motors are chosen, which produce less back emf for the motor driver to measure. ...

Re: Issues with artifacts and over extrusion

We're working on a test pattern generator for calibrating pressure advance. Meanwhile a simple way is to print a single walled cube in vase mode at quite a high speed and adjust the pressure advance to get the best corners. There is some information at https://duet3d.dozuki.com/Wiki/Pressure_advance.

No need to use Matter Control, the Duet firmware has had least squares calibration built in since early 2015. Just make sure you have the Z probe type set to 0 (P0 in the M558 command in config.g), set up a bed.g file, and command auto calibration form the web interface. See https://duet3d.dozuki.co...

What type of Z probe are you using: FSRs under the bed, or something else?

How many factors did you ask the auto calibration to adjust?
