I recently had to move from Marlin 1.0 to 1.1.6 as i mounted a BLTouch and the old Marlin did not have any of the features it needed. I used to get pretty good to great prints out of my 2020 but now not so much. Two issues I am having: 1) it takes a LONG time for the bed to heat. It used to take a while, but now it's mind numbing how long it takes. 2) the thing is trying to print stupid fast.by OneSprague - Prusa i3 and variants
I just re-read the posts above mine. I will change it to 4000. I must have read that wrong the last time - sorry. I should say - i was really impressed with the print quality of the piece I just posted. This machine is pretty cool!!!!!by OneSprague - Prusa i3 and variants
The piece is printed standing up like this: So it's hard to see from this photo, but the circles and the hex hole is squeezed in the z-axis - this is more apparent in person, and the piece is not quite as tall as the one that's getting replaced. I'm making a replacement one as the stock one looses it's bearing all the time, it just drops out of it like so:by OneSprague - Prusa i3 and variants
Ok these are the settings in mine: // default settings #define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,3840,90} // default steps per unit for ultimaker {78.7402,78.7402,200*8/3,760*1.1}920 #define DEFAULT_MAX_FEEDRATE {250, 250, 2, 22} // (mm/sec) #define DEFAULT_MAX_ACCELERATION {1000,1000,5,1000} // X, Y, Z, E maximum start speed for accelerated moves.

So i have been printing with mine for a while and have been working on some upgrade parts. I am making a new X Ideler piece as my lower bearing keeps falling out of it. Only problem is my circles printed in the Z axis are sort of squished down. I have noticed this before and it really didn't mater as nothing had to be precise in that axis, but this piece will need to be or the rods won't be paraby OneSprague - Prusa i3 and variants
Hi, i built my 2020 this last weekend and have a couple of questions: 1) mine seemed to have the X axis flipped so everything i printed was backwards. I figured this out by looking in this thread and following a solution that was posted. Now it homes correctly to X but when it does it moves over, clicks the switch, goes back a little to the left then goes right again and clicks the switch. It doby OneSprague - Prusa i3 and variants
Ok, I'll keep on with my build then and see how it works out. Thanks!by OneSprague - Mechanics

So I'm getting into my first build of a kit and the bed is not silky smooth. If I put my hand on it I can move it, but it seems a bit gritty for lack of a better term. It's just not glassy smooth. Should I be worried about this?by OneSprague - Mechanics
