I give up
 

Magic words!! I just did too, gotta call it quit bcuz I honestly can't make this medieval decade old crap working half-reliably whatever I try. Spent most of today learning this analconda python env, the whole things randomly puts up missing headers although all deps are in, ISE freezes, throws million warnings for no valid reasons, let alone unable to flash a bin over using openfpga among several others I've tried. Just nothing at all works - utter thrash all around in a few words. 20+hrs I'll never have back lool Honestly not recommending anyone to jump in the same bunny hole as I did, annihilates the awesomeness and rep of RIO entirely.

Nuff ghetto. Back to Gowin's EDA. Epic simplicity, less than gig dwload high-performance eda, 15mhz bin flasher/debugger, flawless under linux, ultimate 2-clicks-max joy at a reasonable price. STRONGLY ADVISED.

How to setup gearbox/reducer

Category: Basic Configuration

Hello Todd,
I understand that you make example of "incremental encoder" with quadrature.
My encoder is 17 bit absolute multi-turn type, so the counts for one turn is huge value 131072.
I calculate: 131072*80/360 = 29127.111111. Is it still correct to apply ?.

I put ENCODER_SCALE = 29127.111111 to INI file, but nothing happen.
I understand need to revise HAL file to use ENCODER_SCALE, but it seem encoder component is only suitable to incremental encoder type.
linuxcnc.org/docs/devel/html/man/man9/encoder.9.html

Please advise :) Thank you.

How to setup gearbox/reducer

Category: Basic Configuration

Hi Tommylight,
My system is:
- Drive: AC Servo EtherCAT drive
- Motor is installed in SCARA robot
- The encoder: 17 bit optical absolute multi-turn. Its resolution is 131072, so I understand it has 131072 counts for one turn.
- The mechanical gearbox ratio is 80:1, fixed with motor.
Hope it is all you need :) Thank you.

Ok disregard the above.
There is a component name mismatch as 'tpmod_scurve' currently builds from the 'tpmod.c' file.
I copied 'tpmod.c' and changed the component name in the code, then changed the Cmakefile for tpmod_scurve to point it to the modified file and now it loads.

Do you think a dialog to confirm that you wish to update the probed diameter in the tool table would be better or just always update?

[QTDragon] blocking in hal_manualtoolchange dialog

Category: Qtvcp

What version of linuxcnc?
If you are using the Qtvcp version of hal tool change, there should be a button 'pause for jog'
This was a work around for this type of problem.
It actually works by aborting the program at the tool change and restarts the program after.
You must re-establish machine settings such as spindle settings after the tool change.

Well rod if I can save $20 or so dollars to me it’s worth it. I’ve never had any issues with the company I’ve used. Very professional, very pleased with their service.

 

Be clever and see it on the positive side, I'm barely able to find those QFP144 parts locally, rare af, extinct specie, only supplier near me wants triple price for it. That to say; if you keep them an extra 24 months or so they'll fetch hundreds of dollar. Contact your Technology Museum or Antiques and/or Collectibles agent in 2026, he'll unload them off ya for a good price :)

Investment. See!!

Does sound like the scaling is off

You probably need to check the actual vs commanded RPM
over the entire range to figure out the proper scaling number

In the past I've used a shipping forwarder, might add a little extra time but does save a some money on postage.
 
Pointless doing this for a few circuit boards. Insist it is sent by Fedex or DHL. Let them sort out the customs for you. Worst you can do is pay an extra 5% tarriff into .AU

Things like this coming from Sea I always use my freight forwarder as there are a lot of opportunities to get ripped off.
 

 

True that. Pointless to cut corners for such important hardware, priceless!! I've just sold my nissan and ordered 6 six boards 12 daughter boards and all the mandatory ribbons cabling etc. And remember you need to order X2 (a.k.a. spares), it would be devastating to have a month-long machine/production downtime shall a board decide to have a bad day!!
