Hi PCW. Ok thanks for the reply. This was my backup plan, so I will probably go this route then and leave the modbus stuff for another project.

Cheers,
David

how do i use a img.xz.sha256 file?
I believe that is the wrong file

Hi, I've been trying to configure my Y axis on a bf20 type milling machine for a few days now.
I've read a lot on the forum, but I'm not able to configure it the way I'd like.

I understand that the Y axis, when the spindle moves away from me (or the table moves towards me) should be positive. That's what my Y axis does
I have an inductive sensor installed as a switch for both limits and home. When I search for home it goes to the negative side and I want it to go to the positive side.
I've tried HOME_SEARCH_VEL = 10.000000 and it goes to the positive side, but after home it always hits the hard limits when I get close.

Another issue is that I'd like to change the direction I move the table on the Y axis with the keys. When I press the up arrow I'd like the table to move away from me. 

I would think it would be simpler to use a 0-->10V analog spindle speed control
Also, I'm not sure if the Mesa MODBUS interface would work with the Huantyang

I am just overloaded with other jobs at work right now, didn't even get the one I am retrofitting from mach3 (dead Bob... again!) to linuxcnc to move yet... already working overtime just trying to get the normal repairs done in a normal schedule..

this is exactly what i told to my boss about this shite pneumatic cilinder doing the up / down torch BS... thx Rodw for pointing this out . when you can have the chance to upgrade a machine, then you should upgrade the machine all the way

I have 24V on the 5 pins to the left of the orange screw terminal.

Thanks, what size should the ring be?

Looks OK, can you verify that you have +24V
on both VFIELDB pins?

Hi Chris,

I upgraded to 2.9.3 and would appreciate a hint how to use a custom iu file.

Kind regards
Carsten

I have now solved the issue. Thanks for the help

I contacted the vendor and they advised me to order a replacement card and send the defective one back for review. They also informed me that all boards were tested before shipping and most defects are user error. Now, I only connected what is shown in the pictures for a quick test and the card was not working from the start.

Can someone confirm if I made any errors connecting it? (Not to prove anything to the vendor but to save me from scrapping another card)

"Its alive"!

I think I've found the correct pins in pncof. But when I select the pin for home z axis and it hits the limit switch. Instead of continuing the homing routine it shuts off the whole system and says j3 hit limit in home state. Is the whole point of the homing routine not that it hits the liit switch and then continues the homing sequence for the other axis (I'm homing x first btw). Do I need to select it as a different function? I thought the home function would surely be the correct one

Background: I have a 3-axis benchtop milling machine (PM-833TV) that I converted to CNC. I upgraded to DMM servo motors about 3-years ago and everything has worked like a charm until the hard drive in my HP 8300 died last week. I misplaced my most recent backup HAL and INI files, so I had to modify an older version. They are attached below. I also upgraded from 2.8 to 2.9 after installing the new hard drive. I am using the ProbeBasic GUI. 

The problem: Approximately every other manual tool change, when the Z-axis retracts the spindle to its max travel, I receive a "joint 1 amplifier fault." This is odd because the Z-axis is joint 2. Joint 1 is the Y-axis, which is not moving. Further, when the DYN4 servo drivers encounter an error their status LED switches to red and the drives have to be power cycled to clear the error. There is no indication of an error on the physical Y-axis drive when I receive the fault on the LinuxCNC GUI. Simply pressing the power button in the GUI allows me to resume control of the mill (but it cancels my current milling operation). Further, this "joint 1 amplifier fault" does not occur during long milling operations the rely heavily on the Y-axis only during manual tool changes. 

Any idea what could be causing this? Please let me know if you require any additional information
