I'm about ready to start welding steel. I haven't purchased the steel yet but expect to on Monday 6/21/21 so still time to recommend any design change. This is my 4x8 design and I plan to use the following....
Avid CNC rack and pinion drives and gear racks,
Linear rails on all axis (looking for about 2800mm lengths ?)
I plan to order a Z axis assembly from Amazon to save time.
Nema 34's with drivers from Stepperonline (48 volt) with seperate PS's for each Driver
I have the gantry too high in this design pictured and will be modifying it to lower it. The gantry will also be 2x6x.25 steel.
I've always used Mach3 but my laser has a DSP on it and I really like it. So I'm thinking of going that route with this CNC router, if I could get recommendations on which DSP would be good please.
Any suggestions/improvements or criticisms are very welcome please.
