Hi, maybe this thread could help

Ok, I'll delay the pcb fab a day and see what I can do with those lonely 15 GPIOs. I'll have them all via and TP on the back side of the PCB. 
Fine if I just leave them at their 3V3 logic level? Test pins assuming, [USE WITH CARE, pirate skull logo near lol]

I don't want to seem intrusive. But does anyone have an idea and could help?

thanks! I actually just come from further testing. I must have done something wrong. Because the states of the pins do actually change. Apologies.

How is it mapped now anyway, implicitly?

because on the top of the example-hal file it mentions that limit switches are configured. but i cant find them explicitly:

➜ remora-rt1052-basic cat remora-ec500.hal
# Basic HAL config file for NVEM controller board running Remora firmware
# Configured for 3 joints (A, Y, Z axes) with home and limit switches

Thanks!

@Patrick,

for the vtk error, check the latest sim configs for changes there are many including the var file, Ini File, custom_config.yml, subroutines just about all of them, and the ui has received some pretty serious updates. that is one of the issues of trying to do customizations without using the user tabs. if you decide to make edits i strongly recommend using only the user tabs to do so which are not changed on updated and are loaded from your config folder.

I haven't been able to get 2.9.3 to work for over a month now. more and more new problems... on another machine 2.8.4 there are already 4 goals - everything is fine. I have no more strength. Tomorrow I will roll back to 2.8.4

Have a look into /var/log/syslog and see if you can find anything time-relevant to your issue(s).

Hi pin outputs you can find in the attachment.
Estop has 2 pins, same for probe. Other inputs have one common and one negative for each input. 

#*** AXIS_Y *******************************
[AXIS_Y]
MIN_LIMIT = 0
MAX_LIMIT = 144
MIN_LIMIT = -144
MAX_LIMIT = 0

[JOINT_1]
MIN_LIMIT = 0
MAX_LIMIT = 144
MIN_LIMIT = -144
MAX_LIMIT = 0

Rename attachement keybingdings.py.txt to keybingdings.py
Place into your /config/ folder.

Hope this helps.

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..
