How deep what size cutter where is center? If you can fill in some blanks I can make you one.

Your machine and drawing should reference a X0,Y0 corner or certain spot on the sheet. That way you would line up on that point zero x and y then run. Your gcode should carry you to the starting point of the cut.

The file can be downloaded from the first page of this thread. There is a blue face file another member posted also.

good luck

Try reversing the polarity of the motor, sounds like the encoder is reading reverse of the travel which will move a small amount that the drive is set for as out of position then stops. The loop is closed between the drive and motor so it will act the same regardless of where the command comes from. If this works but is backwards from the command you can change the direction in the Mach software to correct that.

Don
I'll share what I have encountered with my retrofit. My servo are rated at 150vdc 50amps. I started with the Gecko G320X drives. They work good are very smooth and quiet. Tuning is tricky but once you get the feel you can set them to a nice smooth run. The G320X is rated for a max of 80vdc at 20 amps which so far has ran the X and Y with no problems and plenty of power. I have been running this machine for 3 years in a fab shop so it see's a lot of work. The Z axis burns out the G320 after about 6 months. My mill is a bed mill with a large head and just needs more power than the Gecko can deliver. After losing a couple of the Geco's to this I stepped up to a Dugong 160 35 drive. As you can guess it is rated at 160vdc and 35 amps. This drive throws the Z axis around with no problems and can run much faster than I care to move that much weight. Now the draw back of this drive is that its noisy compared to the Gecko and the tuning is done through software. There is a scope in the software for pid tuning to see the effects of dampening which is very helpful in getting it right.
The specs of your motors are well within the specs of the Gecko and they would probably work good for you retrofit. If you use the Gecko drive be sure to put them on a good heat sink, they are very small and won't cool very good on their own. Something they don't mention in the paperwork provided with the drives.

Good luck hope this helps.

I have been using the C10 bob on my machine for a couple of years with Mach3. So it will work. Did you assign the proper pin out to the 2-9 pins in the pins and ports section of Mach?

Does anyone have any info on the Servo Dynamics SDS 1625 drives. This has jumpers where the PID trim pots usually are. Any info will be great, I tried Servo Dynamics but they won't respond to me.

Thanks in advance

I wouldn't use soft wood it has large fiber and doesn't shear cleanly. Use a piece of poplar it has small grain and is hard enough to cut cleanly.
Use a 1/4" ball nose. Is this a router or a mill?

Hi newbie here ,What type and size tool will work best.

Please be gentle  

Regards Dave

Type of tool would depend on the material you are cutting. Size would be the smaller the more detail. I would need to look up the file and see what size was used to generate the code.

I see the file was downloaded 522 times be nice of some of them shared their results and experiences.
