@IRobertI esteps don't change from one filament to another unless you change the diamond shaped feeder for a mk7.
Also if you didn't changed the hardware head/bowden/nozzle to print 1.75. Then you have a world of problems with toons of filament flowing up/down on a bigger area, with filament also bending inside the tube, retracts failing if the heat/speed isn't right. You can, but you will get gazillion of troubles.
Also the tension for 2.85mm filament isn't the same than for 1.75mm so for starters the filament should be slipping on retractions and/or if the temp it's low and generates force the filament will start to twist on itself on the bigger bowden and most probably will split in two inside the bowden (hysteresis).Edited by Guest
The UM2 is built for 2.85mm filament so it's not strange that you're getting strange results with 1.75mm.
Yes, you can use M92 in Pronterface to set the correct e-steps. Don't forget to save with M500.
