DDSCV1.1 3 and 4 axis offline motion controller

[Boyan Silyavski]

Small update with video to follow:

Controller is mounted in my enclosure and after i spend yesterday all day playing with it, i could say- I like it and i am very happy with it.

Machines moves smoothly as ever at 10000/min and 3000 acceleration. Spindle speed is stable. Program time execution- same as using Mach3 or 4.


Manual has some confusing Chinglish elements as to be expected.




Probing works very well but needs some clarification:

First of all there are 2 types of probing:
Where tool position is at the moment or in Machine Coordinates the probes place on the machine could be predefined and probe or another probe mounted there.

Now the trick. It should be done once only.
Put a tool in collet, tighten it at hand but leave it a bit untightened so that if machine pushes it towards bed it will move inside the collet but at same time is not loose.
One must go to probing settings and make sure probe thickness is set to 0.000 and if not set it so and make sure probing is enabled and " at current tool position".
Then go back to control screen and start moving Z towards table. When you hit Z in table, bit will move a bit into collet. So now you are 0 to table in Working coordinates. Use commands and set Z to 0 in Working Coordinates on screen
M0ve Z up more distance than the probe is thick / by the way Z up is + and down is -, toward you Y is - and away from you is +, X left is -, X right is +, the so called right cartesian coordinate system/
Lay probe on table surface / current Z0/ . + of probe is connected to conductive probe material, minus to spindle body or bit, +should be isolated by other material like plastic from below/
hit "MODE2" then "-A" x 2 times and probing starts . When bit touches plate Z goes up depends how much you have predefined in probe settings. If you look now at probe setting you will see a number that may not be your probe thickness. DO NOT CHANGE THAT NUMBER. Its not wrong.

Now you can probe normally, control knows your real probe thickness, even if there is a loss of power.

PRECAUTIONS:
1. When changing G54 with other WCS you lose your probe thickness so you must do that again. Be Careful! Until you figure all out, raise the probe on a sponge.
2. If you program one of the external buttons that could be connected as 0 instead of "start" / when you hit it it zeroes all in WCS / , then when you zero from it, after that you again gave to repeat the probe thickness setting like from the start. I will investigate further but its start to seem that when you probe and 3 axis are zeroed right before that, that means it comprehends it like you want to set probe thickness, not like setting your Z WCS zero.


I will continue later with my findings. Now back to work.
