Fixed Gantry CNC build log
Well folks i thought id start a build log for what will be my second machine.
This one hopefully will be up to cutting aluminium and plastics.
It,ll be useing nema 23 420 oz motors
70 volt drivers.
2005 ball screws on the x and y axis,1605 on the z,belts n pulleys.
20mm thk rail on the x and y and 15 mm on the z.
2.2 water cooled spindle.
20mm aluminium plate for z axis,stepper mounts,and x axis bed.
Theres a bit to come off the height of the gantry when i figure it out,the y axis box section will bolt onto flange plates .they,ll also be a bit more box section added to the frame to stiffen things up.
Its all subject to change at the minute ,the 200x100 mm box for the y is in bad shape deformed both sides,,thoughts are to weld a peice of halff inch plate to the face of it and get it surfaced if need be,im also looking into self levelling resins,but the latter seems a mine feild,.. which to go for?
hopefully i,ll get a stat on the welding at the weekend,cheers.
