Re: New Power Supply / Opening the Bottom

I designed a printable side panel replacement and inside edge bracket to hold a pair of DPS-1200FB 12V 75A server supplies that I am running my upgraded rostock max with! More power than the machine should ever need at 900W each, but they are reliable, cheap, easy to come by, and they exhaust their ...

Re: Yet another Duet-to-HE280 accelerometer probe adapter

Fair enough, and thanks for the detailed reply. I'll play with the accelerometer board I've ordered when it arrives and start looking into FSR bed leveling. Those two appeal to me the most since bed surface material makes less of a difference compared to optical, inductive, etc... Yes the EFM8BB2 ...

Re: Yet another Duet-to-HE280 accelerometer probe adapter

I've already done it. I was planning to release a product based on this but after literally 100s of hours of testing and tuning and I am not convinced that it can be made reliable and robust enough to work with a variety of surface materials, controllers, and printer conditions. So for now I've ...

Re: Yet another Duet-to-HE280 accelerometer probe adapter

It would actually be pretty trivial to make a custom accelerometer board containing the IIS2DHTR accelerometer IC, and the ATtiny85. The schematics are published for the seemecnc board, and if the attiny and accel are both running at 3.3V you can skip all the bidirectional I2C logic level conversion ...

Re: PEI print bed surface experiments

Has anyone else had issues with the 468MP tape coming off the roll cleanly? The edges of the actual tape on my roll seems to stick to the next layer and wrinkle badly as I peel it off the roll. I haven't even tried to put any on the glass yet since I can't seem to get 12" of unwrinkled tape. I ...
