DDSCV1.1 3 and 4 axis offline motion controller

[Boyan Silyavski]

I can not waste my time to argue with you guys, plus may be you are professional machinists and teachers and i learned about CNC a couple of years ago. Some of it from you. if you say its right for you, ok. If you say all the world does it that way, i agree and would not argue. My mistake then.


But i couldn't care less for all that. I am having a strong opinion what is good for me, what saves me time and how jobs should be run in my home workshop. I have extremely flexible and open mind plus a good memory. I use whatever technique for the moment that best suits me. As i said i mostly use material top as Z0 but sometimes not. So if i hit go to Zero and tool digs in material, bad for me, but it does not happen, because when i program Z0 to be worktable, i program save Z movement higher than material+bit and usually XY0 is material corner not center, so that have never happened. Anyway, machines are not to sleep at, and one should be very awake when working. When i am tired or not in a good shape, i don't use machines


I have tried to use collars as the Kyocera engraving tools come with collars. They are not precise neither repeatable to my liking. So from that time on i dont care for collars. Its faster not to use that way of thinking,.

Another good reason not to use tool offsets and premeasure tools. I have a small case of tools which in total are around 1500euro worth. They basically just cover my pretty basic needs. i don't have 10 000 to spare on tooling. Many times i use the same tool for various jobs, materials plus even for various type of toolpaths on same job. Which means every time i recalculate toolpaths as needed. Which means every different time i insert the tool into the collet just enough for the job. I dont see the reason to have the same stickout just the tool to be repeatable, to make the work offset and so on.

And yes Dean, i use work offsets and i know what they are. I think you should have guessed when i am saying something is not working i am talking about after power loss. I will demonstrate the switch imprecision with video. Hysteresis. That's what i am talking about. But good for you that your switches are working right. What i have discovered is that all depends how you read the switch, from the moment that gets off or from the moment that gets on again. There is difference between both cases. So i found that when i read in forums and people said there:"use simple on /off switches" and i thought " well that's too simple, sensors must be better" i was wrong. Simple switches work better.


So let me again explain the simplest way to Z0 and use the probe with the DDCS controller:

1.put any flat bottom tool in collet and tighten by hand, not by wrench
2.lower Z axis until the bit touches the work table, then move z down 1-2mm so tool moves inside collet up. Stop.
3.hit preprogrammed button to 0XYZ or just use controller and zero Z
4.lift Z axis
5.put probe on table and hit A for probing operation / + is connected to probe -to spindle or machine/, probe has insulator at the bottom
6.probe is touched and probe thickness is rcorded
7.now you can use the probe whenever you like, top or bottom or whatever, cause thickness is recorded

-hit Zero all button again and all of the above is lost. So don't do that or just have it in mind


That's all. So simple. i take back my words and edited the post where i explained the 2 touch probes scenario, as i just found that i was mistaken and in certain cases this will lead to error. I deleted it so nobody makes the mistake . So just use the above said or the below variation, which i find better, but you need a Z setting gauge.

variation of the above using Zero axis setter with known length and DTI:

2. lower until bit touches zero axis setter and all is zero there.
3. if Z axis setter tool is 50mm high/the typical one/ , hit Z0 and enter 50mm, hit enter. Now machine knows its worktable zero


SB shared that video with me in a message, so thanks! I decided to share here. Don't ask me how is done, i know nothing more but will write or call the guys to see if they share.They are Russians or Ukrainians:
