Here's a simple model that prints quickly and can be used to check and calibrate a number for factors.
QuickPrint test part - 20mm x 20mm x 5mm tall so it prints quickly to check:
- X-Y scaling - particularly for delta printers to verify delta arm length
- Z scaling - although only 5mm tall, you can use it for a quick Z calibration test
- perimeter print quality - with two radiuses and two sharp corners you can check a variety of perimeter issues as well as print speed, acceleration and "jerk"
- first layer quality - simply stop the print after the first layer is complete, cool and peal to measure first layer thickness. This measurement should equal your first layer height set in your slicer
- top layer quality - slice with 3 top shell layers to check the quality of the printed part
Slicing recommendations:
- 2 perimeters
- 2-3 shells top and bottom
- 25% infill is good for a quick test print

I have a D300VS+, and printing this guy I'm .15mm to tall and I'm about .75mm too big in the x and y directions. Any thoughts? Rod length is correct, not over extruding.

ReplyDeletestart by correcting the X-Y scaling by adjusting the arm length as described. Then correct the Z scaling by adjusting the steps/mm as described. That's the way it's done. One of my D300s needs steps/mm set to 410 to get perfect part heights.
