Thank you. That is a great help.

The testing of small hole reaming was most informative as well.

This is a gcode issue, what software did you make the code with? Ive been running the new firmware non-stop as well as the factory and its not had any faults yet. Ill run your code to make sure i get the same.

Its Mastercam. Same gcode works fine with cnc controlled by NCStudio. Also, any simulator will show the difference between video and simulator.

Hey Chris, has there been any update on the DDCSV ver. 2 you mentioned back on pg. 28?

@antonio

Testing backlash, is it not using it at all or is there an error in the arc? please run with line 113 on then off to compare. Turn off only if you mach has the same steps per/mm x/y

This may take a while. How is that one version working for the most of you?
Is it stable enough to be used productively?

Hi! I flashed this firmware to my cnc and have a problem with arcs.
Here is short gcode and video:

gcode: https://gist.github.com/arrowcircle/30017c506a6883d7ab227eae4f3af698
video: https://youtu.be/jDDHNsdZgHQ

Problem is, when it makes second tab it does not stop and goes additional 360 degrees without lifting a tool.

Is this a bug? Or do I doing something wrong?

Hello Pekka,

My pictures are embedded, but you apparently have to be a member of MEM to see then. I started off looking at floating reamer holders for smaller holes, 1.5 - 2 mm. I found the Hemingway version but felt it was too big. I also started on an own design with swinging links (attached) but I think it would have required some centering springs. Charlie has explained his version and I have attached the picture that go with reply #3 the Clarkson version.
I also found details of a Swiss version (attached) which in the end I purchased.

http://batzberg-manufaktur.ch/documents/Floating%20Reamer%20Holder.pdf

I carried out a series of experiments with different initial drill sizes and different reamer feed rates which are documented in the MEM thread. I obtained the manufacturers data for the reamers I was using which resulted in much higher speeds and lower feed rates than I started with.

Status update:
My controller is now repaired and seems to be operational again.
I have started to binary patch the latest version of the firmware that has been posted by chriscnc.
This may take a while. How is that one version working for the most of you?

@ChrisCNC, please provide some info on the FPGA registers. This would really help!
Don't fear anything. There is no way we're going to steal any profit from you.
We've got most of the software source (minus the comments and the names of the functions local variables) already, but some FPGA doc would really help.

Beat regards,
Benedikt
