Setting different machine configs for slow and fast spindles is a great option. I don't know how much you'd have to pay for a proprietary controller to be able to program that. But when it comes to spindle orientation (horizontal vs vertical) I thought you'd just use G17/18 and program the parts in CAM with the setup you want. At least that's the standard practice described in the Philips manual and the same codes are available in LinuxCNC as well.

I thing you are right, g17,g18,g19 is a better way compared to separate configurations.

Most CAM systems assume that the tool is aligned along Z (and, in fact, LinuxCNC assumes that for canned cycles) to having the spindle aligned along the system Y can often be annoying.

I will quite often MDI stuff that way anyway, but if using CAM then I have to change config.

And then there is the question of arbor-cutters . I am not sure if any of the CAM systems are very good at that...

Hi All! Today I successfully started all 3 axis and setting axis zero position. But I can't configure PID's to work normally. Axes works with rough FERRORs, up to 1 mm.Can you share your PID settings of your machines? And i have trouble with gearbox. When i trying to set spindle speed gearbox motor 1 moves and mechannicaly stops at end CW position. Reverse don't works. All connections is correct. What could it be? Thanx.

There is no point sharing PID settings, they will be unique to each machine.

Is your machine also a 400E? Here is the axis set up part of my INI, to give you a starting point.
Code:
#******************** # Axis X #******************** [AXIS_0] TYPE = LINEAR HOME = 100 FERROR = 0.5 MIN_FERROR = 0.2 MAX_VELOCITY = 45 MAX_ACCELERATION = 50 P = 6.5 I = 0 D = 0 FF0 = 0 FF1 = 0.22 FF2 = 0.0021 BIAS = 0 DEADBAND = 0 MAX_OUTPUT = 10 ENCODER_SCALE = -1000 OUTPUT_SCALE = 10 OUTPUT_MIN_LIMIT = -10 OUTPUT_MAX_LIMIT = 10 MIN_LIMIT = -1 MAX_LIMIT = 400 HOME_OFFSET = 0 HOME_SEARCH_VEL = 0 HOME_LATCH_VEL = -10 HOME_FINAL_VEL = -1 HOME_USE_INDEX = YES HOME_SEQUENCE = 1 #******************** # Axis Y #******************** [AXIS_1] TYPE = LINEAR HOME = 200 FERROR = 0.5 MIN_FERROR = 0.2 MAX_VELOCITY = 40 MAX_ACCELERATION = 50 P = 5.5 I = 0 D = 0 FF0 = 0 FF1 = 0.228 FF2 = 0.0015 BIAS = 0 DEADBAND = 0 MAX_OUTPUT = 10 ENCODER_SCALE = -1000 OUTPUT_SCALE = -10 OUTPUT_MIN_LIMIT = -10 OUTPUT_MAX_LIMIT = 10 MIN_LIMIT = -1 MAX_LIMIT = 251 HOME_OFFSET = 250 HOME_SEARCH_VEL = 0 HOME_LATCH_VEL = 8 HOME_FINAL_VEL = 40 HOME_USE_INDEX = YES HOME_SEQUENCE = 1 #******************** # Axis Z #******************** [AXIS_2] TYPE = LINEAR HOME = 370 FERROR = 20.0 MIN_FERROR = 1.0 MAX_VELOCITY = 45 MAX_ACCELERATION = 50 P = 7.5 I = 0 D = 0 FF0 = 0 FF1 =0.218 FF2 = 0.002 BIAS = 0 DEADBAND = 0 MAX_OUTPUT = 10 ENCODER_SCALE = 1000 OUTPUT_SCALE = -10 OUTPUT_MIN_LIMIT = -10 OUTPUT_MAX_LIMIT = 10 MIN_LIMIT = -1 MAX_LIMIT = 376 HOME_OFFSET = 375 HOME_SEARCH_VEL = 0 HOME_LATCH_VEL = 10 HOME_FINAL_VEL =15 HOME_USE_INDEX = YES HOME_SEQUENCE = 0
