Mate - That does look good - well done, Do you have any more construction details and photos?

Hi Vertigo
Try these guys - they fit your specifications - I have got a few things from them and they did good by me.

General Mach Discussion / Re: KSI Labs Centipede Controler Board

« on: July 15, 2012, 02:44:17 AM »

Hi Kent
My servo's are 10,000 counts per rev. 3000rpm maximum speed, to run at full speed I need 500 kHz for 1 axis.
The answer to your question is found by multiplying your servo's maximum rpm by the counts of your encoders and dividing that number by 60. (eg: 10,000 x 3000 / 60). You may need 3 axis' to run at once so that will increase the need by 3.  Find out the specifications of your motors and encoders and go from there to find out if 100 kHz will be fast enough.

Hi Rush
Well I did buy a set of the centipede control board, breakout board and cable and have used it off and on for about a year. It does what it say's it does, It is reliable, It has a mile of inputs and outputs. And for a stepper based system I would recommend it highly. As far a speed goes it's no better then a parallel port - but for inputs and outputs it's great. They are also extremely well made.
I used it in my Lathe which has high count encoders and the centipede was not fast enough so I moved to a Ethernet Smooth Stepper (which are also not perfect but fast enough).
Sergey is working on an add on board to bring the centipede speed up as well as a lot of other features such as closed loop control and when this happens I think the centipede will be the pick of the external motion control systems.
So yes I do recommend it if you don't have a servo system with high count encoders. (the new add ons could be out any time so keep an eye on his website).

Hi Brian
If the video can not be done and I understand George's reasons for that, what would be the chance of small written article on what is to be said at the seminar please? I am keen to find out what our next steps are going to be, especially on the hardware front - I don't want to buy anything now that might be useless when Mach4 arrives. It doesn't have to be until after the public announcements are made at the seminar.
Thanks
Steve

Hi Brian and George
For us poor devils on the other side of the world who can not get to this event and like myself very interested in Mach4 and it's features would there be any chance of making a video of this talk and posting it so we could get a peek at what the future holds for us?
Thanks

General Mach Discussion / Is Calibrate Spindle Working?

« on: April 30, 2012, 01:27:49 AM »

Hi
I was wondering if someone could check if the "calibrate spindle" function is working for them in version r3.043.062? I has worked very well for me in the past - I can't remember the version of Mach I used then but a move to the Ethernet Smooth Stepper has seen some hardware changes for me and a move to a later version of Mach and I would like to recalibrate my spindle speeds. My symptoms are that the spindle doesn't start during the auto calibrate process. I should say that I do already have it going when I start the auto calibrate but it stops at the first speed command (which is zero and it should stop then) and doesn't start again at the higher test speed commands.
Thanks
Steve

Hi GD.
Please post a link to your project on the zone - it sounds like it would be a good read- I have done a search but the place is so big and hard to find articles on.
Thanks
Steve
