Nice job! It looks like new. Can you help me with another mather . Which pull stud are you using the thing on the SK40 tool holder?
I can’t find one that will clamp into my microne.

Bestr regards

Hey, how is your progress? I have some small adjustments to make on mine and then hopefully I will run my machine on the end of January 2018
Still having some position correction we are talking 0.005mm the motor is constantly searching for the position.

CS-Lab / CSMIO IP-A and linear encoders ( seting step per unit and encoder pulse/rev)

« on: March 31, 2017, 12:37:20 PM »

Greetings altogether. My problem is so simple and yet I tried everything and no solution.

My linear scales are from ISKRA and they are 5um and this is 0.005mm (the seller told me that they are 0.5Um and now I found out they are 5um)
Anyhow, I have to set two parameters one is in the section Mach3-Config-Motortunning-Steps per unit.

Ok I contacted the Support after a month of trying different calculations and numbers and the answer was:

If you use a scale then you take neither ratio nor screw pitch into account.
Your task is to indicate pulses number per 1mm and the scale will help you with it.
 
>>> The resolution of linear scales is: 5µm this is 0.005mm
 
It's very easy:
 
1mm / 0.005mm =  200 steps per

Ok and now what is the Encoder Pulses/Rev: ( mach3-config-config plugins-CSMIO motion controller configuration)


Does anybody know please help.

Best regards

CS-Lab / Re: Motor tunning with CSMIO/IP-A (PID) Trouble with encoders

« on: March 25, 2017, 12:41:57 PM »

Ok I have changed the servos and from Friday morning I am trying to tune the motors with no success. Now I am questioning my input data.
Please chek my calculations:

I am using Kinco servo motors and for feedback position linear scales. The resolution of the linear scale is 0.5µm if I convert it is 0.0005. To get the PPR  I divide the Lead of the screw wich is 5mm with the resolution. And the PPR is 10000.

Now if I want to calculate the steps/per I just divide the 10000/5mm and then i get Steps per=2000.

If I set this parameter into the Mac3 and start auto tuning it finished but as soon as I tried to move the axis I get e-pid fault and in case I change the max error to a larger number i get sudden movements by jogging.

The transmission between ball screw and motor is with gears.

Can anybody please help me? what am I doing wrong.


Best regards

Greetings,

i have been also working on my machine these past couple of months.  To sum up what i have done so far.
I have changed  the energy chain and the linear scales. Also i have painted the whole machine. Now i have changed the operators panel
and added an cabinet for the new drivers for servomotors. For now i will stick with the gear transmission between the motor and spindle.
Will add a movie of my progress as son as i find some time.
Also the tuning is going to be a pain in the A**.


Here is also my thanks for HOOD he has helped a lot ! Thank you !


Best regards

Greetings Davek 0974

Have you solved the problem? I have  some similar problesm with the asuto tuning. I have  new motors servo motors and drivers from kinco, also the linear scales are new  Iskra. I have tied the auto tune
but it simply does not work properly. I'm starting to lose faith in the csmio controller.

Before changing the motors i have used the original bosch driver and dc motors and i have managed to tune them porll. But there was another problem as soon as i pushed the button go to zero and after that stop
the machine started to go in some kind of a auto tune state.  I have contacted the spupport  and they have said i should send them the mach file. Now its about 4 months and still no answer.

So im a litle disapointed.


Best regards

Did it cost alot of money ?
How hard is to change the spindles ? Are you considering also to replace the Z?
Yes that would be great . Im waiting for the motors now.


Thank you for your help so far !

Where did you buy the spindles ?  Did you bought the spindles longer then they were in original ?
I have bought new motors and meanwhile im waiting for the motors im going to prepare everything for the belts.
