Higher end Chinese controllers?

[Boyan Silyavski]

Yes that's good enough for me and agreed impressive if it can buffer without pausing in the cut. Have you tried cutting at high feeds/accel while the buffering from USB.? IE 3D cutting. This will be the Acid test.

the fastest cut i have done for now is 16000mm/min at same time trochoidal and no glitches. yes dean, it cuts that 7 million file without sto and any problem loading from the USB. I stopped it at half as i had another job. Then loaded it again and ir read the whole file and started from the middle without problem. But i will do 3d test when i have time these days.

Explain how it does this please.?
Does it home to separate switches for each side/axis or are you using the Index pulse from your Servo drives and just sending signal to one input.? This will make difference to Stepper users who don't have Index pulse and use slaved motors.

As you know i have the 3 axis controller so not 100% sure, but lets say 99.999%

It homes Z, then X, then Y and i assume then A / when A is chosen not to be rotational/ . So there is posibility how many mm to back off after homing and how many times to home/ 0-5/ . I have it set at 2 times, it goes to Home, then back, then slowly homes again, then moves back what i say.

-So without homing anything we make sure the gantry is perfectly square/ using straight edge across rails and precision square/
-then we move the gantry to end of rails / i home at side near me, you choose that from positive.negative homing direction option/
-as Limit switches Leds are on we see which switch is hit first. So we move and adjust them so that left switch Y is just a tiny bit in front of right switch A.
-We adjust backoff after homing at something small like 1mm / which is nothing for out of square for 1800mm gantry like mine for example/

-we hit home,it homes Z, homes X, then goes till end and homes y backs off 1mm and then homes A and squares it backing off 1mm -now that have to be checked if will work and move the 2 axis together, i will know it when i have the 4 axis controller. But even that has a walkaround. We install a button/switch on enclosure. When we hit it it mixes together the step/dir signals of the 2 long axis when homing. So both move till the end as one together. When all is at the end. We switch it off and we home again here. No problem - Each axis will move only 1mm so not a big deal , but all will be automatically square

As you see that last one will work for sure.

I square at the moment/ with the 3 axis controller/ home all. No back off. From A servo controll panel move as to turn Led on limit switch off/ as i have previously adjusted then with the square edge so they light and off at exactly same time
