Re: Tormach 1100 vs. Haas VF3
So what I am reading here is that the HAAS is preferable as a training tool (at $65k) vs the Tormach ($9k + $3k enclosure) for two reasons:
1. The HAAS enclosure has a micro-switch to shut down the machine
2. The HAAS FEED HOLD actually stops the machine at the next feed command (vs Tormach that stops the machine after the buffer of commands that have already been sent to the machine is executed).
My solution:
1. Buy the Tormach enclosure and mount a $5 micro-switch on the door, wired in-line with the micro-switch for the spindle door.
2. Mount plenty of remote e-stops. Yes, it sucks to use the e-stop, because you lose your reference, and have to eraser the machine and the part (there is 3 minutes gone), but it is better than sinking a end-mill in the table. Yes, feed hold is more convenient than e-stop. But is it $53k better when this is just a teaching/training tool, not a production shop?
I am rather surprised that Tormach doesn't have a micro-switch on the enclosure door already (after all they sell this as an "educational package"). I would suggest calling and talking to them about this feature, if that would be on of the things that would prevent you from buying the Tormach for this application.

Tormach is releasing a new PCNC linuxcnc software edition next week. It would be awesome if it saved this problem as well.
