With no hardware info, this is just a guess. If you have encoder feedback, swap A and B to reverse count.
For steppers, invert direction.

Be ready with E-STOP when you test, things can go very wrong quickly.

Learning HAL and external offsets

Category: HAL

Hello,I have a project where I want to apply changes to a cnc toolpath in realtime based on object tracking data from a camera. I have been told that while uncommon, that it is possible. Particularly, to use a hardware abstraction layer to apply external offsets so that the original g-code remains unchanged and the toolpath can still be updated. However, as a novice and having done a deep dive into this topic, I find it very difficult to complete this project because of the lack of information on these topics. Can anyone direct me or recommend how I can learn how to use HAL and external offsets? I have also been suggested that parametrized g-code is dynamic and can work. That Fanuc controls have a feature called real time macro and Siemens controls have a feature called parallel program execution, which I may be able to code in linuxcnc. Thanks!

I2C - 5V (hope this will work via the level-shifter)

Maybe a good and cheap universal-board

That's just awesome!! Never thought of using the w5500 lite module as a board add-on, great idea. That would have simplified a whole lot. In the other board gossips, here's another fully functional/tested Gowin based RIO Motion Control Board. Surprisingly everything works flawlessly and so I'm upgrading this from a prototype rev 1.0 to alpha, and getting ready to start on a beta release (revision 1.1). Should be out and avail for testing in a week.

Video about shielding cnc machine wiring

Category: Computers and Hardware

I was hoping he would have shown a twisted pair in comparison, oh well. I usually do twisted pair wires more to
keep things tidy, though shielded cable is best.
Something to note if a cable is to be continuously flexed a braided shield is better suited for things like drag chain
cable carriers at least in the long run and industrial settings where the machine maybe operating 24/7 365 for
years on end.
Still it was a good video showing the scenario.

Category: Driver Boards

The 7I97T has 6 hardware encoders, you do not use the software
encoder.  Your sample looks like a parallel port configuration.

I would suggest using MesaCT to create a hal/ini configuration file set.

LCEC creating Danfoss VFD config

Category: EtherCAT

 
Hey folks,

i'm trying to retrofit an old Maho400E in the near future with a Beckhoff EM7004 in combination with a costum adaptor-board for the 3 axis and wanted to prepare the electronics as far as possible. In addition to that i also want to implement a Danfoss VFD FC302 with its EtherCAT optioncard MCA124. I started to read out all the PDO mappings and so on, like in many other forum posts described, but now i don't know how to proceed with the Flag E and the dmesg output, that the VFD would not support distributed clocks. You can find all configs and readouts of the VFD on my Github . The most important stuff is also attached here.

Thank you guys for your help

Best regards
Patrick

Plasmac2QTplasma gives error not a Plasmac configuration /solved

Category: Plasmac

Thank you for you kind reply and offer, no worries , the error is on my side not being up to date, you are all busy enough.

I had a 7i76e.pncconf file which I was able to open with pncconf and my settings were there at least seems ok for the default machine.

I was using a xbox controller, a two button crane control with emergency stop and the laser was with a M7 command- button set to the mist hal output.

I will read the documentation and hopefully get all working with the qtplasmac machine setup again.
I assume the additional config is the same, custom hal etc.

thank you
Roman

Voltage encoder with 7i97T board

Category: Driver Boards

wanting to configure my spindle encoder and reading linuxcnc doc for Spindle Synchronized Motion I found out that the encoder must be connected to mesa card inputs and not to encoder input 5 (7i97T).
Do I have to change my encoder wiring or is it possible to do the same as
# Add the encoder to HAL and attach it to threads.
loadrt encoder num_chan=4
addf encoder.update-counters base-thread
addf encoder.capture-position servo-thread

# Set the HAL encoder to 100 pulses per revolution.
setp encoder.3.position-scale 100

# Set the HAL encoder to non-quadrature simple counting using A only.
setp encoder.3.counter-mode true

# Connect the HAL encoder outputs to LinuxCNC.
net spindle-position encoder.3.position => spindle.0.revs
net spindle-velocity encoder.3.velocity => spindle.0.speed-in
net spindle-index-enable encoder.3.index-enable <=> spindle.0.index-enable

# Connect the HAL encoder inputs to the real encoder.
net spindle-phase-a encoder.3.phase-A <= parport.0.pin-10-in
net spindle-phase-b encoder.3.phase-B
net spindle-index encoder.3.phase-Z <= parport.0.pin-11-in
