Re: How much gantry curvature is too much?

I have had two M2 printers - the first was returned under warranty - but both needed to have the X rail shimmed to get a good first layer on large parts. I haven't seen any significant issue on the Y axis. One thing I'll say about using an indicator is that even with the Rev E 4-point support the be...

Depends on how my wife will feel about burning the adhesive off in the oven. Might get stinky.

TIP - Removing PEI Sheet from substrate

Have a well-used PEI over Aluminum bed that has started to release the PEI around the edges. The 3M adhesive sheet has dried out around the perimeter and doesn't have any stick left. The center however is still well bonded and I was not looking forward to trying to pull things apart. Wondered if fre...

Re: How to solve this printing problem? (ABS printing)

I generally run the layer height at about .5x the nozzle diameter, and lately I've been matching the extrusion width to the nozzle diameter (based on good results with another printer). If I were going to print ABS with a .35mm nozzle, I'd use a .35 to .40 extrusion width and a .175mm layer thicknes...

Re: How to solve this printing problem? (ABS printing)

What nozzle diameter and layer thickness are you running? 0.35mm nozzle and by layer thickness do you mean extrusion width? If so, its set at 0.45mm No, I mean Layer Height. I've never tried to push a bead that wide from a .35 nozzle - don't know if that's a factor or not. Your temps should be high...

M2 parts (and other stuff) are posted here: https://github.com/MakerGear
but I don't see a section for the M3.

Re: acceleration and jerk minimal settings and starting scri

I have recently used the website http://gcode.ws to get better estimates of build times. It takes jerk and acceleration into account where slicer estimates I've seen don't take those settings into consideration.

Re: acceleration and jerk minimal settings and starting scri

I have found that things are pretty clean with X and Y at 900.
I have settled into using a JERK setting .1x the XY acceleration.

M201 X900 Y900 E5000 ; acceleration
M205 X9 E5000 ; jerk

I usually run at
M201 X1600 Y1600 E5000 ; acceleration
M205 X16 E5000 ; jerk

for faster print times.
