Amazing work! I am currently converting a haas mini mill, and not too familiar with the ribbon cable coming from the keypad. What side goes to what pins on the mega? I tried to read the sketch but couldn't work out the pins. I would be very grateful if you could assist me! I also have the pcb from the board with the rs port. I did see someone was working on that way too.

Many thanks Chris

Hi,

i have a rather ambitious project on my hand. I need to convert my Weiler DZ26 as of today my old 810T control finally went the way of the dodo.
I´ve put so much time and effort into keeping that old thing running and making it jump through hoops via CAD/CAM and my own postprocessor, but enough is enough.
My plan is to get basic turning functionality working and look into millturn operation later.
In general the machine is a dynamic (20m/min), high acceleration monster(for its time), with a super quick Sauter 12 station toolchanger (all stations driven).
I plan on using the original Siemens drives and motors. Both spindles need to run in high- or low drive modes for A-axis operation and toolchanging modes. Both spindles have two encoders for high rpm operation and low rpm positioning. The Control need to switch a number of accessories like coolant pump, self oiler, solenoids for mode switch of the tool changer and so on...
I will start with a kind of allright office PC to get it up and running and plan on switching to a proper industrial PC later on.
From what i have read over the years if you have a dynamic machine, your better served with PCIE based mesa boards.
My current plan is getting myself a 6i25 and a 7i77 breakout board. Should have enough I/O for my needs and PCIE should keep it rather real time.
Do you have any suggestions and/or questions? I will document my progress over here and definetly need some help every once in a while.
What would be your recommended GUI for a machine like that? I have next to no experience in LinuxCNC, but are pretty decent in all kinds of Siemens controls.

Best,
Lukas

Hello Community,I am looking for some expert advice on replacing an old Baldor VFD, model INV-0054, used in our Fadal VMC4020 milling machine from the year 2000. We are considering upgrading to a Delta VFD and would appreciate any guidance or recommendations on selecting an appropriate model.

 

Hi PCW,

Sorry I am unfamiliar with the terms that you are using. 

It seems that TTL mode is transistor-transistor logic? Is this the mode the board should be operating in?  Even after the firmware update?

And push-pull means that there is a mosfet or transistor opening the input to ground when the pulse is off/low, correct? I guess this makes sense with a pull up resistor, now sure why they would have one there.. And then obviously high when the pulse is on. I do not know if this is how the Powercore is wired.  Honestly, all I know right now is that there are two wires coming off the ALRT pin from the Powercore, I am assuming one of them needs to be tied to ground and the other is the PWM pin.  I think there is a schematic online I can look at and try to find out. 

If the board can run off the 3.3v straight from the Powercore that would be great, if not I can figure out what I need to change and make a little circuit. Wether thats a push-pull circuit or with a simple pull-down resistor. I can also increase the voltage if I do that..

Thank you.

Best,
