Plans for this machine:
If anyone has any suggestions at all please shout. This is the first time I have attempted to rebuild a machine of this nature in this manner.
I will add more photos of the machine as it is at the moment tonight or tomorrow.
1. Try and find compatible (and affordable for testing only) software and drivers so as to try and make it run as is so as to test all screws, limit switches etc.
2. Find appropriate 4 or 5 axis controllers/kit to replace the current set with.
I am thinking of using this kit:
Stepper Motor 3 Axis CNC controller Kit NEMA 23
Package Contents:
3 X M335 Microstepping Driver
3 X Stepper Motor NEMA 23
1 X 5 Axis Breakout Board
1 X 24V 15A Power Supply
1 X LPT Parallel Cable
1 X USB Cable
1 X CD Driver
Actual parts in kit.
I want to use as much of the current parts as I can so will not be buying more limit switches and so on for now.
I wish I could keep the current stepper motors in place but it seems it would be cheaper to replace them for my intentions.
3. Lower the working table as much as I can and raise either the X, Y or both rails if at all possible so as to increase my Z working area.
4. Do extensive cut tests in both 2d and 3d, cut pyramids, domes, planed angles etc and make sure everything is running perfectly. Modify whatever needs it.
5. Cut some plates to fit the new parts into the current controller box (there is plenty space inside it) for the new breakout board, stepper motor drivers, power supply and whatever else needs it. Modify and improve airflow and ventilation so that the new parts don't produce excess heat.
6. At this point I may or may not decide to add an A Axis going down the right side of the working table (I may even cut or mill myself an area for the motor and working space to fit into but want to make it removable in case I want to engrave larger things on the entire working table).
7. Once the machine is complete, installed and tested I want to tear the whole machine down, do maintenance on all the screws, bearings, moving parts etc.
8. While all the plates and frame are separated from the electronics and mechanics I want to respray them and possibly personalise them
9. Final step is to put the whole thing together and hopefully get years of play time out of it.
I want to mostly cut plastics and wood but would also like to be able to cut into softer metals as well. Will the NEMA 23 motors handle this?
