It is working. But I used large motor with DQ860HA driver. 

My first machine was in 2021 working with bob.

this is the first mesa 

Good day

 

Ok I see.

I have three seperate inputs from the selector switch that are exclusive to each other (only one active at a time).

I would need 3 mux components, one for each axis for my different values right?

Typically this would be done with a mux component.

If you have 3 inputs, you could use a mux8 component

If the 3 inputs are binary coded, you get 8 separate scales.
If the 3 inputs are linear select (just one input active at a time),
you only get  3 selections but mux8 will still work.


 

I can move the servo motors manually and see their position. However, I don't want to have to go to home because the encoders are absolute. The image of the side screen doesn't appear on mine either... I don't know where I can adjust the ratio because I have a reducer. I also couldn't move it automatically once.

So, I still haven't been able to move forward.
I haven't been able to properly understand how Linux CNC works... so I'm following the tutorials here but without a knowledge base, that's what's holding me back now.
Would you be interested in doing some consulting to help me? Because I have to hand it in at college and I can't do it.

Hey all,

I am about done configuring my milling machine. One of the last things I need to do is set the mpg scales for my 3 handwheels.

All of these handwheels use encoders with different pulse/rev so I always need to assign a different scale to each axis. I want to have 3 speed settings and have already connected a 3 position rotary switch to select these settings. The three input pins for that are working fine.

I tried setting the values with a variable assignment in classicladder but can't seem to get it to output a float value.

All of the scale values I want to set are float values.

Does anyone know a solution for this?

I need to look at my GS20 VFD docs. I believe there was a parameter that I may have set to prevent to only allow the Spindle to run between 5k and 24k. So we can probably not waste unnecessary cycles on the spindle not stopping.

What I am concerned about is the tool length measurement. I am attaching an image which shows my rig.
Note that the setter BASE is BELOW the table top but, the setter TOP is ABOVE the table top by some 10mm.
In the QTDragon setup I have entered 10 for the height which I believe is correct?
How do I setup so that tool measurements are consistent?

 
 

Does the machine use any serial port?
There are again several errors trying to access the serial port called from the scorbot-er-3.hal file, but this time it has no access to it (permission denied), so omit that line in hal.
Or if it has a serial and it has to be used, try searching for
arduino serial port permission denied
to add you user to the "dialout" group.

I now have a Dell Optiplex 9010 i5, with a DB25 Parallel Port and a RS232 9pin port. I created a LinuxCNC 2.9.2 live DVD boot disk for it, and are still waiting on a SSD drive to arrive for this computer. I plan on using this computer and LinuxCNC to run my Scorbot-ER-3 Robotic Arm. In my previous question I thought the supplier was sending me a Dell optiplex 980, but shipped the 9010 instead. When I try to run the Scorbot-ER-3 example I get different errors then previously, but believe this is due to no hard drive. Is anyone aware of any LinuxCNC issues with the Scorbot-ER-3 machine example in 2.9.2?

I would try standard 7I96S+PktUART firmware (using
the TB2 RS-485 interface) and then work backwards to
find out where the issue is.

Pictures of everything?

Thank you for the reply and for the chart! Navigating Mesa's selection for a novice is very confusing.

I completely understand, but you might be surprised what you can find used for that price. Take this one on Ebay for example.
www.ebay.com/itm/256470069304
It is only priced at $2500 and looks like it has a tool changer. (Although the vacuum pump for part hold down would cost extra.)

schau mal hier , da gibt es noch ältere Versionen.
