Should I switch from AXIS to QtDragon?

Category: Qtvcp

AXIS has better keyboard shortcutrs in theory, though many of them simply do not work for no reason at all in reality.

My mouse on the PC is poor (I dropped it on the hard concrete floor a couple times).

The keyboard is PS/2, I have lots of keyboards, but I am low on mice.

I have no quality mice available.

Should I switch from AXIS to QtDragon?

My CNC PC has a nice 1920x1080p 60Hz LCD over DisplayPort via the iGPU.

It has no dedicated GPU.

Determining Angular Scale - Help w/ Microsteps

Category: Configuration Tools

Okay so i confirmed that 1600 is the number, but this just makes me question what the micro steps are doing. Its clear i don't know what the step/rev actually translate to.

I guess i am just looking for what the optimal dip switch stetting is for my setup and what this number should be.

This software seems to have a decent scope as well. Is there any reason i shouldn't use this to tune the PID and get it close before moving to LCNC? It just easier when its all on the test bench. I know alot of wiring noise factors in it final resting place will make a difference but could i get it close here? or would the new environment completely change the PID settings?

If the power supply can do over 2A of current, yes you can use the same supply.
And no, that 2A is not related at all to the 2A written on the drive.

Hi Friends, 

catching up on replies now, i was out traveling for work the last few days. Here are the links to the motor and driver i am using. 
Motor

Driver


Ill try to reply to everyone in this one reply to avoid any confusion, and ill to to work backwards as much as possible. 

@Langdons
 - Does speed make a difference?
No it doesn't seem like it. The Arduino code i am running does  a slow loop and a fast loop changing the delay int between steps and its been consistent every time. Although i haven't cranked the speed up and don't plan on it. 


@andypugh
- you are correct, i am trying to understand the most optimal way to get this into Lcnc and based on previous posts I can maybe modify the drivers software to make that a whole number. Still investigating this though. 

@timo
- I have and it works as expected and repeatably. The issues comes up when i put it into the pulley system, with the reduction i can't hone in a precise step/rev, from which i can derive the steps/deg for a rotary axis in LCNC. 
- in regard to the pulleys, I am certain the motor pulley isn't (the ole sharpie method) the idler doesn't count, and no am im not 100% certain that the drive shaft is fixed in place, however with everything powered down i can turn the drive shaft and it turns the motor pulley. that on top of the low speeds and it being uploaded gives me a decent amount of confidence in my answer. 
- I also haven't even begun to tackle any of the encoder/ pid error stuff because when i tried initially i discovered this the issue we're dealing with now, that comes next once i have this setup pretty good. 

@spumco
- This is my plan. I have the cable and am able to get it to talk to my PC, the issue is once i get it its all french to me. How would i verify the 4:1 encoder resolution? Should the drive be connected to the motor when i do this? I am going to spend the next few hours messing with it on the software side and ill report back what i learn or how i mess up. 

Thank you all again,

Driver:TB6560 JP-1635A 
Steper:  57hdd0401
In your opinion is it safe to connect this driver and stepper?
Can I use the same 24V power supply that I use to power NVEM or is it better to use a separate one?
I only need it to test the jjdege conf (if I'm not mistaken it's the same conf as mine then it will tell me nvem-rt1052.txt)
to check the outputs.
I will never use this driver-stepper as a final solution.

You won't need to develop a driver, you just need to write an xml file.
the wiring is substantially reduced using Ethercat drives over mesa.
Do you really need an encoder? The only purpose I can see is rigid tapping but thread milling is more efficient and it does not require it.

Everything about Ethercat is more expensive but it is the emerging standard. It does add a bit of complexity to the config. The bit that is not really worked out is the internal drive homing but using Linuxcnc homing is just as simple as mesa. I've had good luck finding reasonably priced Beckhof modules on ebay (including encoders) but some are outrageously priced, more expensive than new modules.

Ethercat with rs485 controlled VFD is the simplest way to run your spindle but there is now a linuxcnc driver for Omron mx2 VFD's .

its just all round better if you have a 1080p rouch screen, plus it adds probing and too handling if you have repeatable tooling.
it is very well documented

Thank you all for your time for NativeCam, 

Does the configuration for the lathe work?

Milling machine and plasma work without any problems, unfortunately configuration but lathe does not start

Thank you for your help

Sorry -- I missed this reply earlier. No, nothing specific. But the machine (and the axis preview) seem to do the right thing.

After homing X and Y, can I auto move to a non 0,0 location?

Category: General LinuxCNC Questions

Also make sure you read this entire document:

linuxcnc.org/docs/html/config/ini-homing.html#_home

It seems like HOME is the INI variable you need to change.

That drive and board require Quadrature outputs, LinuxCNC can do that easily, but i have no idea if Remora can do that.
There are 9 or 10 stepgen types that LinuxCNC can do, and probably 3 of those should work.
And just to be clear that "drive" is not a drive, it is an array of Darlington transistors that can handle 500mAh, if i recall correctly.
Apparently there are 15 types now, just checked so i need to update myself from 2008! :)
