Re: Question: Home switch placement
Homing Y positive is the default, because that is preferable on most milling machines. You do not have to use the default. You can set your homing directions to whatever you want. The direction any given axis homes (and the order in which the axes home) is determined by the instructions in the cncm....

Re: Is it okay to crank the servo motors by hand on my Allin1DC mill?
Yes, it is okay to do that. I am fairly certain that, with power released, the Allin1DC essentially disconnects the motor, so there is no energy to absorb. But, even if it were in a dynamic braking mode (and you would know that when you tried to turn the cranks) the drive should still be able to dis...

Re: How does acceleration work in the centroid control system?
It works the way you expected it to work: the accel time and max rate settings establish the acceleration rate.
That acceleration rate applies to all moves, regardless of the final speed.

Re: Rigid Tapping Question
The "G Code Tutor" reference applies to some controls in some configurations, but it is not universal, and in this detail it does not apply to Centroid. When you get into the finer details of canned cycles, there is a lot of variation between control manufacturers, and even between differe...

Re: Rigid Tapping Question
I am going to ask where in the Centroid manual it says that it will still rigid tap with an F value by figuring out the pitch from the RPM/Feed. You could just try it and see. Verify that your spindle encoder is working correctly, and that you have set Parameters 34 and 35 correctly. Set bit 0 of P...

Re: Kollmorgen AKD drives
More useful would be a picture of the preceding screen: the one with the live display of values such as Error, PID Out, Abs Pos etc.; and with the status window and message box visible. After you get a "410 ... position error" stall, and you press and release emergency stop, and then you p...

Re: Recovering information from CNC7
How transferable are the PID settings? Only somewhat, and then only if you read them right. The values displayed by CNC7CONV include a scaling factor of 256, so what you had was Kp = 1, Ki = 0.004, Kd = 20. With the Allin1DC you might start with Kp = 1, Ki = 0.004, Kd = 3 If you get an unacceptable...

Re: Kollmorgen AKD drives
There is no voltage on Oak pins 25 + 26. The SUM on PID screen ramps up to 2560000 and stops then I press jog and Oak faults out. Drive wont reenable until i cycle power to Oak. There is no need to cycle power. Just press and then release your emergency stop button to clear the stall/fault conditio...

Re: CNC12 and RS-485...
You could try some experiments with M120 and M223, to write text to a serial port that you have configured. If that works, then you could write your own M3, M4 and M5 macros to send appropriate commands to the spindle drive. You will, of course, have to devise some separate way to ensure that the sp...
