"PREVENT_COLD_EXTRUDES" or close, IIRC . . . - Tim The way I see it, if the extruder is not hot, you might not get an accurate measurment on the 100mm extrusion.

Quotetadawson I spent some time thinking about this, and now my head hurts . . . . steps/mm on a delta are on the tower drives, not actual X/Y/Z directions . . . so, the only direct relationship is when all three towers move together for Z movement, then you are 1:1 . . . for X and Y, the delta calculations are in the middle. So, if, say, your X print dimension is off, you can't simply 'do the maby mmcginnis9272 - Delta Machines
Quotebluesmike I haven't measured but lets say I print a flat square that is 50X50 - it prints fine. If I try to print a flat square that is 100X100 it starts to lift as it traverses from y to x steadily. It doesn't seem to jump just slowly rises. It sounds like a very common problem in which your firmware is not tuned to your rod lengths. I would issue a G28 to home the machine. Then manualby mmcginnis9272 - Delta Machines

I recommend: 1. turn down your Polulo reference voltage. (This can cause other problems if yoby mmcginnis9272 - Delta Machines
Although removing the LCD has fixed your issue, the true culprit might be a weak Ramps board. Removing the extra current of the LCD could be alowing the Ramps board to sustain the needed current to operate.by mmcginnis9272 - Delta Machines

Got my Foldertech 2020 2 weeks back and have loved it - been printing in PLA for a while and I figured it was time to do some upgrades, so I wanted to print out a new effector and mount some new rod lengths - anyways long story short I got some ABS to print.

QuoteDeguello Quotemmcginnis9272...extruder with the mounting ear cut off? I used the acrylic mount that came from Folger, so the mounting ears are superfluous. (The rubber band goes to a clip on the wire loom to the effector) I see, that makes perfect sense. I was not near my printer and I was thinking the printed mount is what attached to the openbeam.

Quotethevisad QuoteWittmason Haha yeh the mechanical fixes were from me. Funny I was referred to that. This is more or less not enough torque from the motor.

I left the motor mounted on the frame using their mount. Wby mmcginnis9272 - Delta Machines
QuoteWittmason When I've had this happen on my last 3d printer it was because the nozzle drug through the parts and the steps got offset when the belt slipped. If you set the z lift on layer change to something like 4-6 mm that should help. Did you mean .4 to .6 mm? 4-6 is a huge raise for z change. I use .4 with good results.by mmcginnis9272 - Delta Machines
