Brother TC-225 / TC-229 adventure!

It sounds like something basic is wrong with your LinuxCNC setup
Its unlikely there is a major error in the TP that others have not noticed.

Can you post your current hal and ini files?

I have not shipped the machine yet. I am waiting for my employer to setup their warehouse so I can move it in. It should happen in a couple of months. The industrial controller I was looking at is a Delta NC311. When combined with the A2 style drives and motors it is supposed to auto tune, which is appealing. I have not heard much about the controller, so I am a little worried about support. I was hoping since it setup for drill and tap centers it would include some optimization of the tool change process.

Either way, I plan on replacing the motors and drives. I am just not sure what I am going to use for a controller.
LinuxCNC is appealing because of its flexibility and cost, but I don't want to spend a huge amount of time tinkering.

ill see if I can get that tomorrow night when I go to the shop.

I imagine its possible I changed a setting that's causing this, but ive not changed anything relating to that I don't think.

its almost like a threshold. if I run a circle (2 g3's) at some speeds and radii it respects g64, and at others is stops between arcs.

I wish there were more examples online of successful tuning of analogue servos. theres only a handful, and they don't tell you anything - or are on low performance machines.

ive looked at the delta control a bit. I am seriously considering the asd a2r servo drives for the tc229 but they wont autotune the stock motros

theres also the siemens controls, which at least here in Toronto have good support. they don't cost a lot relative to equivalent controls, but all of them are "kinda bit bit too much to spend on a $1500 machine" so I am trying to exhaust all the cheap as free options first.

Note that with properly tuned velocity mode servos, pretty much all the "high performance" aspects
are controlled by the drives, not LinuxCNC, so major difficulty tuning velocity mode drives really points
some kind of setup issue.

that sounds logical, (especially since we know the drives are fine under the brother control)

.... but whats is the setup problem!!!!



can you just come to my house and fix it? hahaha.
