DDSCV1.1 3 and 4 axis offline motion controller

[Boyan Silyavski]

Its very simple. It assumes you have a zero setting gauge. You hit the gauge and move until is Zero there. Knowing that the gauge is 50mm high you zero the machine. When you hit zero Z, you enter 50mm and now machine knows where bed is. Next put whatever isolated probe on bed and hit Probe. Now it figures the probe thickness.

But hit a button that zeroes all 3 axis together and all of the above is lost. Does that make sense to you?


So lets chew it up again:

In order for you to use automated probing without any further hassle like above, one very simple modification should be made to machine. Mount your probe / VDC+/ on the machine directly, so that + does not touch bed in any way. So that probe surface must be actual table zero level. You can do that by pocketing your bed if metal, fit a plate there connected to +, epoxy it, wait to dry and surface it on bed level. You could even tell controller where that is so every time the probe goes there to check tool offset. or just buy 2 of the cheap 3 euro chinese spring probes from ebay and integrate one in bed.

So once you have that probe level with bed, you could either use another probe or use only this probe

edited: dont use the method i said here as i found a serious mistake from my part, in certain scenarios. Use the mechanical method described above or several post below.
