I realize OneFinity does not support 4th Axix but for those who are using the Y or X axis as a 4th axis does anyone have a best settings for the stepper motor? I’m using M1 and want to use good settings for it. Maybe a couple of screen shots showing the setting you use for step angle, velocity, acceleration, micro steps, etc.?
Here a piece I cut for test purposes to check the precision/measurements.
I am about 0.25mm oversize, that not too bad.
If I lower the Z by another 0.1mm I should be spot on.
I did not care about surface quality for the test. This was done in 35 minutes.
Again, the Onefinity is a very precise CNC. I love the hardware.
Thanks Tom. I have all of that nd used the settings and Post Processor. What I am looking for is best settings. As example I know that the Velocity of the motor is better at 7200 and the Max. Acceleration is good at 500. So what I am looking for is any changes made in those and other settings of Motor 1 that give you the best performance and decrease the carve time. To do something like this on YouTube. When I set up Mother Mary file the carve time was 36+ hours.
I personally am looking for precision rather than speed, i have slowed it down and noticed the surfaces came out much cleaner.
max vel 7m/min.
max accel 500
max jerk 750.
That probably won’t help, you can run your machine much faster if speed is what you are looking for.
I think if you want to reduce carve time it is best to work on your tool setting. Why not remove 1.5 or even 2 mm per step when roughing out. Also the stepover for finishing can be more like 20-30 percent, if the tool is small its less noticeable. If you finishing with a R1mm tapered ball instead of a R0.25mm that will save a lot of carving time, it might be 4-8 times faster. I would recommend playing around with tools and speeds.
At the end a bit that fits the job might set you back only a few dollars but save a lot of machine time.
The video looks totally off to me. I can clearly see the tapered ball bending, and surface quality is pretty bad. I would rough out with a 6.35mm ball end first. But it’s fast. Not what I am looking for
Here are my current Motor 1 settings. Seem to be working OK. Will try to carve an ornamental candle stick holder in the next few days. 3”x7” in MM settings.
I’m using a Skinny Jenny 1/16 ball nose for the finish. I think I can save some carve time by changing the step over from 10% to 20% and the feed rate from 120 to 150.
