Title: Slow axis feed rate is too fast
Post by: wade16 on August 03, 2014, 09:17:11 PM

When I press the arrow keys for x and y axis and page down for z axis, the feed rate is too fast. How do I set the slow feed rate for all axis?

Pressing the Tab key brings up the pendant - reduce the Slow Jog Rate %  :)

I  did that  and that helped. When the slow feed percent was set at 100%, the feed rate moved at 6 ipm. Is that the default rate for Mach3?

I think the default is 80%

Yes, when Mach3 starts, it defaults to 6 ipm.

I add a feedrate to my initialization string, so the feedrate is higher when Mach3 starts.

Can the default slow feed rate be set lower without having to adjust the pendant setting?

Be careful not to confuse Feed rate with JOG rate.
The G1 Feed rate defaults to 6 IPM, the slow jog rate (% on the pendant) defaults to 10% on mine regardsless that persistant dro's is checked. Version R3.043.022. On other versions, I thought the Slow Jog % rate would stick, maybe not. ? ? ? ?

Might just be coincidence that your max speed is 6 in motor tuning .... but doesn't seem likely that it is that slow.

I was mixing up feed rate and jog rate. I set the pendant  jog to 20% and it does stick. I think that fixes that problem. Thank you for your help.
