Hello.
I have constructed a 3D router measuring 1000mm x 500mm, using stepper motors lead-screws and aluminium extrusions generally as used in 3D printers. It is controlled by an Arduino board and drivers. It all seems to work OK.
My problem is that when a workpiece is clamped in position; the zero point (and hence the cutting operation) seems to migrate in all axes by up to 50mm even though I am testing the machine on polystyrene insulation board.
My process is:
1) Create a 3D model in Pro Engineer and then export it in STEP format.
2) Open the STEP file in Fusion 360, create a toolpath, simulate and export .nc file and copy it to a memory stick.
3) Take the memory stick to the garden shed (where the router lives) and try the cut using bCNC or preferably Universal G-Code Sender.
If anyone else has experienced this phenomenon please let me know if you have any solutions. Indeed any advice would be appreciated.
Thank you.
