Amadeal25LV CNC Conversion

[StevenT]

My mill is about 3 years old and used mainly for making clock parts, the reason for converting to CNC is to speed up the cutting out of clock wheel's and plates and to move away from cutting by hand with a fretsaw.


I am using the original lead screws but replace the cast iron nuts on the “X”and “Y” axis with Acetal nuts made to the method described by Evan Willams.http://bbs.homeshopmachinist.net/thr...s-the-easy-way.


The backlash with the new acetal nut for the “X” and “Y” is X =0.08mm and Y=0.05mm, on the “Z” axis I have fitted a gas strut to control the weight of the head which also looks like it is controlling the backlash, but I will see how it works in practice before making any more modification.


For software I plan to use FreeCad > HeeksCad/Cam > LinuxCNC.


Next phase will be to buy the stepper motors and controls, which will be in October due to Holidays.
