very slow moving cnc

[Anonymous]

im using MacOSMajave on my macbook pro. For some reason my cnc walks super slow before starting to cut. once it has reached start point it goes normal speed. If i use my friends windows computer i dont have any problems the speed is good. I haven changed any settings in creating gcodes . Even deleted and reloaded new fusion . its just supper annoying to watch it go so slow . is there anything i could change in settings? I understand its in gcode . But i dont really speak gcodes. will post few pic for better idea whats going on .

At the beginning of G code you have G0 rapid move code with F100 (100 feedrate). G0 X1056.51..

I don't know why there is feedrate declaration in combination with G0, but I guess that in this case contour speed of all moving axis will be 100. Maybe this is to slow for you, and you can delete feed rate designation F100 (than machine will be moving axis as quickly as it can when calling GO) or increase that speed.

But be careful if changing speed in g code and be ready to stop machine if something goes wrong.

Best regards,

That behaviour is written into your Gcode,  

your first move command, G0 .......  has the F100 will be updated by another F command.

The next F command is in a cutting command and is F2336.8 which is an odd number but could be a calculated value.  Lower the number, slower she goes.

I don’t use Fusion CAM so don’t know where the setting is to be found, 

will be Speed for Rapid Travel in the set up stage, to look for.

Might help....
