"All that time" is maybe 3 to 5 hours a day, Jon. All of what I post is from this master machine of my home network, before or after the "greasy" part of the day. And because I've a bad back comfy chair here, that I don't have room for where the machines are, much of the code I'll use the next day is actually written & tested in a sim version on this machine, but the sim is working, thru an sshfs net link directly to the nc_files directory of the machine that will execute the code and run the motors the next day. Some would call that part of the working day I guess. :) ATM, working on parts I can't buy from ebay, because the next round of orders will be around the 11th. Parts like the spacers and how they attach to the machine, or making the flange/nipple combo's that will couple the loooong bellows the Z screw will be covered with. And I've still not figured out where to put the cable chain to the saddle at. On TLM, its anchored to the top of the spindle motor box, goes to the right and turns clockwise to point back to the left and anchor on top of the x screw shielding. Serviceable but out in plain sight ugly, and high enough "most" swarf curls out under it. I may follow that same form, from a bracket on the rear edge of the bed behind the spindle, to fold over and back to meet a dropdown bracket on the rear of the saddle. That low will be a swarf magnet, so I'll probably put an upside down u section roof over it. Hang it off the rear edge of the bed, bolted to it beyond the normal saddle motions. Not quite as ugly at least and a good place to put limit/homing switches. Now all I have to do is find the suitably bent sheet metal. :) Or a brake 60" long I can use for half an hour. :) IOW, this project is far from done. :( Many thanks for your help in making your pwm-servo run a big dc motor stolen from a treadmill for the spindle of TLM. Or the OEM DC 1hp rated but choked by the OEM controller on that G0704. I now have the power to slip a TTS toolholder in a 3/4" r8 spindle collet, with the drawbar well tightened on the TTS, almost at will.
