Nice work on the update to probe_basic. The status tab is perfect! I see this is an older post, but maybe you can share the update or some notes on how you made it. I want to create something very similar. Newbie here and not sure where to start.

None of the axis are moving - using mesa 7i92t with 7i76u

Category: Basic Configuration

Hi All
Yes, the W4 jumper on the 7i92t was down, and it is now up.
The linuxcnc config loads, the inputs also work , and there is also movement on the motors

A very very big thank you, to the knowledgeable folks on this forum, for sharing your valuable time, wisdom, and knowledge with me, it is greatly appreciated.
As a person new to Linuxcnc , there are so many things that we don't know.
Be braver than me, post a question sooner than I did.
(For folks reading this post in the future, the wiring currently is differential, and seems to be working fine).

Warning: Spoiler!

At the risk of the blind leading the blind, to me that is not quite the right question. That chart is for your micro-stepping. Like the 800 is 4 microsteps, if you're using a 1.8 deg. stepper. I have always looked at it this way - What are you doing with the motor? If your opening a door or driving a ram, picking 800 would be fine, but using that on a belt or lead screw may very well end up leaving artifacts in the work due to the rougher movement between points. The downside is the more micro-steps you have the more torque you lose. 3200 (16 micro-steps) seams to be a reasonable middle ground that most use as standard. The controller will put out as many steps as directed by LinuxCNC to make a revolution, just a matter of how fast it can do it. Whatever you chose, that gets figured out when you tell LinuxCNC in your .ini file how many pulses it takes to move one unit. That is set with the SCALE on each axis. Like for me, I have 16 micro-steps (3200) and a 5mm pitch screw, which works out to SCALE = 640 or -640 depending which way you need the motor to move.

Thanks for reply,
I have set 12800 and testing some gcode only with Y working.
I don't want to cause problems when all the stepper and spindle are physically working.

Question on Servo analog output scaling

Category: Advanced Configuration

Yes, unless you set the analog scale so that it equals
the velocity in machine units per second at 10V, (and FF1 ==1.000),
You will need to tune FF1 using halscope.

Here is a long thread about this tuning:

Today I managed to modify the hex file as proposed above by removing the EOF lines are sorting the sections. This way I succeeded flashing and all buttons of the matrix keyboard are now finally working. Thanks Peter for the firmware.
I really wonder why all the tools, I also tried more modern versions of the MPLAB X IDE, are not able to properly read the original hex format.

Why not just build a deb and install your package?
github.com/jethornton/simple-deb
github.com/jethornton/simple-pyqt5-deb

Or if you're using Flex GUI you can just add it to your ini and it gets imported.

Yeah sorry about that mate.

Shipping is a killer to Down Under. I've used shipito as a forwarder and gotten good value on previous occasions.

I've previously used a Spartan 6 Dev board\Colorlight board (spartan 6 based ones are hard to find now) as a smart serial card based on Mesa's 7i90 hostmot2 firmware. Unfortunately it only supports digital I\O and 4 encoders for use as hand wheels. No analogue nor keyboard functions and not quite as compact as the 7i73.

I had FF1 at 0.05 before and increased it to 1.000
However, the axis began to vibrate and commanding a jog resulted in a really high follow error, so the machine engaged the e stop.

Thank you all for the responses!

I inquired with iC-Haus and it looks like the chips will work just fine for me. I'm currently in contact with them to get a price offer. Even better that they're based in the EU.

It'll take a bit of time to cobble together a PCB with said chips, but it's looking promising and I'll post an update with the results.

hey murph, i think scott said the outputs were just optocouplers or something like that, see if you can filter through his recent posts,

pheonix, like spyder said its based on application, but start with like 800-1600 and if you get following errors its too high

I didn't mean for this to turn into a debate.
I have had great support from Mesa and they make quality parts.
The freight is not their core business but is the weight around their necks for sales into Australia.

I was just hoping to get a better deal if able to combine costs. Better products and service and reasonable freight.
