Check what you have your filament diameter set to and measure your filament in 5-10 places and take the average. The software usually sets it to 2.85mm but sometimes it can be higher or lower than this. Put in the average value for your specific filament. I’ve had some filament come in at 3.01mm.
Assuming that is correct, bump your flow rate up a percent or two, print, and measure again and see if your OD distance is better. I always assume my part will be off by about 0.2mm and account for this on my press fits and dimensions in my design.
I did not know this was a option and would like to do that for sure! Is this cube just a say 20x20 cube? Or is it a test print that I can find in the software? Also where are the firmware options.
Yes just download, slice then print a 20X20X20 cube or make your own. Then measure it and if it does not match the dimensions you used then adjust the steps in firmware.
Look in the Configuration menu on the LCD just above the ESteps. Or if you have a Mini you can use gcode commands like M503 to see what they are currently set at. This command also gives you the commands to use to change them as part of its output.
So I found a fff. file that finally got my Simplify 3D to work(well kind of). So I printed the same part I had dimension issues with and to my surprise it is a heck of a lot closer than the print that came from Cura. Its still not perfect but way better.
Cura part - .235"
S3D part- .245"
So Im closer but pretty disappointed that Cura is that off.
I did a quick extruder cal where you mark 110mm of filament them extrude 100mm and measure whats left. I measured 9.89mm so I would assume that I am over extruding.
Side note maybe someone can help with this and not start another thread.
this new fff. profile for S3D at the end of the print it doesnt move in Z off the part. Instead the head moves in X till it hits the limit switch which is not good because its dragging the head across the part.
Look in the end gcode section for your simplify3d profile.
Curas looks like this:
M400 ; wait for moves to finish
M104 S0 ; hotend off
M107 ; fans off
G91 ; relative positioning
G1 E-1 F300 ; retract the filament a bit before lifting the nozzle, to release some of the pressure
G1 Z+20 E-5 X-20 Y-20 F3000 ; move Z up a bit and retract filament even more
M117 Cooling please wait ; progress indicator message
G90 ; absolute positioning
G1 Y280 F3000 ; move to cooling position
M190 S0 ; set bed to cool off
M84 ; steppers off
G90 ; absolute positioning
M117 Print complete ; progress indicator message
