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

Category: General LinuxCNC Questions

Well... that's certainly a unique machine.

And a good demonstration why 40ipm is a realistic top speed.

OLD Lathe conversion to a CNC

Category: Turning

Today I reproduced the problem again. When running code with
G96
(constant surface speed), if I stop the spindle and then start it again, the spindle runs at 40–60% lower RPM than expected.If I resume the program at that point, the cutting feed does not adjust to the reduced spindle speed, which can be dangerous. After that, I stop the program, and Gmoccapy looks like it does in the attached screenshot.
 
 Then, if I reload the program and start it from the beginning, the machine suddenly runs at a crazy high speed, and the graphical interface also shows the actual (high) speed.

Spindle Gear changing was created by dctrytsman

Spindle Gear changing

Category: General LinuxCNC Questions

Can someone please explain how to set up gear changes. My lathe spindle motor is connected to a gearbox that has two gear ratios and the gears are changed by a pneumatic actuator. The gearbox is then connected to the spindle via belts. The spindle has a encoder connected to it via a 1:1 geared belt drive. The feedback part of the system works fine.

How can I connect this to HAL so that the machine automatically selects the correct gear based on the requested spindle speed. I think that the gear change should take place when the spindle speed is very low, but not standing still as the gears wont change smoothly.

First time to try build my xml for not listed ethercat in-out component

Category: EtherCAT

bkt, something you mentioned before.
If I understand right, there is a master module "S1-M20" and a connected sub-device "ECL16DP"
Both are EtherCAT devices or slaves. They should both show up as slaves when you do the "ethercat slaves" command.
But in the lcec_configgen listing there is only the "S1-M20" module, identified by the line
<slave idx="0" type="generic" vid="0x00000b3d" pid="0x29c9f7b1" name="D1">
where vid and pid are the numbers for S1-M20.
The config you are working on now is the S1-M20 config because of that.

In the first post you attached ESI-files for the ECL16DP unit. Identified by the lines
<VendorId>0x00000B3D</VendorId>
<ProductCode>0x1201B602</ProductCode>
in the xml file. That's the device with the inputs+outputs.

If they both are EtherCAT devices (and not meant  to be accessed through the S1-M20 in some way)
they should both show up on the EtherCAT bus. Use the command "ethercat slaves" to verify that.
They got to be visible on the EtherCAT bus before you can access them.

Long initialization of Ethercat on servo drive SV660N

Category: EtherCAT

I have had long sync times, and there recently was a user that went from debian 10 and igh 1.5 to debian 12, igh 1.6.3 and latest linuxcnc that experienced long time sync times. I switched network adapter which helped a lot, but there was no solution for the other guy.
In the dmesg list, you can see that the client's time is converging, it's just that it's converging too slowly.
One thing you can try, that doesn't solve the root cause, is to restart linuxcnc after such a failed start.
The thinking being that the clients now have a much better starting time for the time sync.

Tool changer

Category: O Codes (subroutines) and NGCGUI

Hello,
Could you please help me with my tool changer, my machine is cnc endmill  emco 55 pcmill. I am using Carousel Component with counts mode, since I have a stepper motor on the tool changer.I also have a sensor that connected to sens-0 (index)at this point I can move and home the car, I can also do the tool changes.the last thing that I need to do is move the carousel back home once the tool has been changed. How can I move the car back to home with a subroutine?My tool changer does not have an arm that I can control.

Thank you,

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

Category: General LinuxCNC Questions

Heh. I would have to say probably "yes", to both. LOL.

It's a DIY mill. In 1993, II got it as a kit, which included the stepper, a driver board (which did just raw coil driving -- not even step/dir!) along with plans for a chassis made of particle board, rails from high quality drawer slides, and all-thread rod as the transport. The s/w that came with it was written for DOS, polling loops and all.

There have obviously been a lot of upgrades over the years: EMC/LinuxCNC in 2004, acme rod for X and Y (Z still uses the all-thread) a lot of chassis strengthening, a real step/dir driver board maybe 10 years ago, and a Mesa card and Raspberry Pi this year. But it still has the same steppers, and the linkages and threaded shafts aren't all that well aligned. Frankly, I'm amazed it all kind of still works. But I have fun with it... when it's not driving me nuts!
