Unfortunately setting #307.6 = 1 doesn't seem to prevent 4th axis alarms from putting the machine into Not Ready state as soon as the control is enabled. Not sure if it just doesn't work as expected...

There is a parameter #307.6; Disregard signal for fouth axis is effective = 1, Inefective = 0. But it seems to expect an input. There is no switch on the machine. No idea what will happen if I set it...

I have an old Matsuura machine with a 6M-B controller. For years now the Z-Axis VCU has a habit of blowing the main/alarm fuses on the same phase at unpredictable times and getting replacments is...

Seems to have been solved by leaving gains alone but enabling LowPass+2X on parameter 29. Need to put covers back on and test to be sure.

Does anyone have experience tuning HAAS servos?

I have a 2007 HAAS machine here that's just had the Z-axis ballscrew and support bearings replaced. The locknut on the bearing block had come loose...

I'll take a look when I'm back on Monday.

Hey John,

They're Fanuc 11M's with a Seicos sub-system. They were both working until I put my hands on them, bit sad but we couldn't find a buyer.

We pulled a couple of these apart late last year to make room for new machinery after failing to find a buyer.

Structure, frames and panels went to the recyclers.

Servos, ballscrews,...

Compared to my existing machine yes. However, there are obvious drawbacks to rigidity with a modular design, depending on the quality of the coupling connections between modules.

The prototype block was a little... bricky.

This is what I've done on this project.

The idea was to develop an automated design for CNC machined CNC machine actuator, made from wood-composite panels.

Hi,

I thought I should post some progress on my new machine design/build to get some feedback before I move to the next phase.

My design is for a fully parametrised generic linear actuator that...

Hi A_Camera, awesome machine.

This is for a university engineering project, so I need to be able to back up my design choices with reference to published research. Those that I've found show that...

Actually, now I'm confused by some testing results I'm getting.

I replaced the Chinese drivers and breakout board with a mesa 7i76 and geckodrives in anticipation of getting better performance out...

Thanks.

For the hybrid machine, I'd like to aim for a minimum feed rate of 40 mm/s, 2400 mm/min while 3D printing/digitising/laser cutting. This seems fairly achievable given the fact I can hit 30...
