Fadal Format 2 = G73
I'm running 88HS in Format 2. My G73 peck cycle works fine, but it does not rapid between holes. It moves pretty slow to each new position to drill, which will cause me to die of old age before it's finished. The posted Gcode Looks okay to me. Is this a Fadal G73 Macro issue?
I have to try it again, but I think a regular drilling cycle worked fine

Re: Fadal Format 2 = G73
Looking at the canned cycle docs in the Fadal manual it says:
"Format 1 & Format 2:
If one or more axis moves appear on the same line as the fixed cycle, the cyclewill be executed at the specified position. The cycle will execute at the end ofthe move. The move can be a G0, G1, G2, or G3 move. The feed rateestablished before the cycle line is the feed rate that will be used for thepositional moves made with G1, G2, or G3. The feed rate on the cycle line willonly affect the Z axis move."
Okay, if I'm reading that correctly, if the initial move to get to the first set of coordinates was a G0 then it should use that? But it's not. Then it goes on to say the move would be a G1, G2, G3 at the same feed rate as the initial move. If the feed was G0 for rapid speed, does it do a G1 instead? So if G0 will do 700 ipm on my machine, but a G1 only does 400 IPM then it's not really the same feed rate is it? I don't think it's anywhere near 100 ipm between positions, let alone 400 or 700.

Re: Fadal Format 2 = G73
change your SETP to format 1 does it work ? looking at your program it should be positioning in G0......... or hey try this put a G0 on the first move after the cycle is created

Re: Fadal Format 2 = G73
I can give that a shot and if it works I can edit my post.
Like this....
