Send me a printer without endstops, and I’ll end up ripping out all the wiring and doing my own from scratch.

apparently these days you can have printers without endstops… if only using a modern control board :smiley: but this is kind of hear-say as i dont have a duet to try it :smiley:

I would only have a printer without endstops if the axes employ positional feedback.

Anything else relies on a memory of where the printer thinks the axes are which might not match reality.

Y’all are about four years behind the times :stuck_out_tongue: the Makerbot Gen 5 used stall detection to replace XY endstops in 2014. (Not that I’m saying the Gen 5 was a good printer, but endstops weren’t one of the big issues.)

In fact, most printers in the early RepRap days used dead reckoning for XY where the user just centered the print head before the print… works totally fine. (Z is a different story of course, but you should be probing that anyway, right?)

The Prusa team has been using it on the MK3. They did just mention that they have had issues with repeatability so I wouldn’t say it’s totally beneficial
