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,

Thank you very much, you are very kind, I have been trying to change the configuration for days without success, now it is perfect, we will see how it works in practice.

Thanks PCW, was hoping to get your opinion before I did it. I will give it a go.

what button can use, select linuxcnc 2.8.4 debian version, select X or Y or Z axis, and then select use continues or 1mm or 0.1mm or 0,5mm need this because have lot easy use on table remote keyboard wireles mini, than go ewerytime use display and mouse select how many step move. 1mm or 0,1mm or0,01mm and 0,5mm or 5mm or etc. when search wood piece zero corners. manual. i not can add automatic G-code 38,2 system alltime come only errors lot.

The 7I96S encoder inputs have a 1.65V threshold when jumpered for  TTL mode
so will work with a 3.3V input. They do have a 2K Ohm pull-up resistor to +5V,
but this should be OK if the 3.3V output is push-pull.

If you have a couple of probes you can always flash one with the following firmware.

Hi Scott

I have two ST Link v2, flashed the CMSIS-DAP firmware to one of it.  When i plug this in either Windows or Linux PC i dont get a new drive for drag&drop operation of the Firmware ? It this working different then shown in your "Remora RT1052 DAPLink Programming" Youtube video ? Also i cannot find the firmware you have used in those video anymore, was this replaced with the FW linked above ?  I need to flash a NVem with rt1052 Chip

and a BIG thanks btw for your great work

edit: seems like i need to use the pyocd to flash tool

Is this what you are looking for?

There are precision levels, one brand is the Taylor Hobson Talyvel. It has a small sensor unit that is about 5" square, and can easily detect arc second changes. Slipping a human hair under one end drives it completely off scale.

I have one obtained surplus on eBay. it reads out to 0.1 arc second and after factory calibration is supposed to be accurate to 0.2 arc second. When I put it on the bed of my 3500 Lb. lathe it easily detects the change when I walk from one end of the lathe to the other. The advantage of this is it has magnetic damping so that if you pick up the sensor and place it on a surface, it settles within 2 seconds! A water level or oil bubble master precision level takes at least 30 seconds to settle.

This is doable, take a look at this thread:

forum.linuxcnc.org/38-general-linuxcnc-q...o-7i92-boards#311116

You can use mesaflash to change the EEPROM IP address
(probably to 10.10.10.11)

Hello Mates,

I can't access wiki for 15 days or so, is it out? Other than archive.org, is that another url?
