Hi Robert First of all apologies for the length of this post, I have added the actual text from the gcode as I could not figure out how to attach a text document, sorry! the test file in the pictures goes like this G17 G21 G91 F800 G01 X0 Y-43.175 Z0 G01 X9.675 Y0 Z0 G01 X0 Y43.175 Z0 G01 X9.675 Y0 Z0 G01 X0 Y-43.175 Z0 G01 X9.675 Y0 Z0 G01 X0 Y43.175 Z0 G01 X9.675 Y0 Z0 G01 X0 Y-43.175 Z0 G01 X9.675 Y0 Z0 G01 X0 Y43.175 Z0 G01 X9.675 Y0 Z0 G01 X0 Y-43.175 Z0 G01 X9.675 Y0 Z0 G01 X0 Y43.175 Z0 G01 X9.675 Y0 Z0 G01 X0 Y-43.175 Z0 G28 The original file I was using went like this: (however I never made it past the first few strips as i noticed it was not doing it right) G17 G21 G91 F800 G01 X0 Y259.05 Z0 G01 X-9.675 Y0 Z0 G01 X0 Y-259.05 Z0 G01 X-9.675 Y0 Z0 G01 X0 Y259.05 Z0 G01 X-9.675 Y0 Z0 G01 X0 Y-259.05 Z0 G01 X-9.675 Y0 Z0 G01 X0 Y259.05 Z0 G01 X-9.675 Y0 Z0 G01 X0 Y-259.05 Z0 G01 X-9.675 Y0 Z0 G01 X0 Y259.05 Z0 G01 X-9.675 Y0 Z0 G01 X0 Y-259.05 Z0 G01 X-9.675 Y0 Z0 G01 X0 Y259.05 Z0 G01 X-9.675 Y0 Z0...

I appreciate i'm answering my own question to a point here!: I went on to Amana Tool Website and found there feed rate sheet, so for my tool (45199) it was listed as (IPM) 110"/0,0031, for softwood. To calculate Feed rate in IPM, the calculation given was - RPM x #flutes x chipload, so my calculation was 22000 RPM (no 3 setting on the workbee router head) x 2 (number of flutes) x0.0031, =Feed rate in IPM = 136.4. A quick google conversion gave me 3464 mm/min. I don't think i am going to start at this level of feed rate, it does seem very fast to me, however I am a newbie and I don't want to break things, so I do ask if this feed rate seems plausible?
