Adjustable feedrate and spindle speed

It would be nice to be able to make a percent adjustment to feed rates while running, and to adjust spindle speed while running.

I couldn’t agree more. Being able to increase/decrease the feed rate of a carving while it is running would be a great way to help you set the optimal feed rate for your project. Mach 3 has this feature for both the feed rate and spindle rpm. Of course you can adjust the rpm of a Makita on the fly and if you have a VFD driven spindle then there is almost always a manual RPM adjustment options available there. So in reality, for most of us, if OneFinity could add an option for a feedrate override, I think that would awesome.

I think another nice option would be keyboard shortcut controls for Jogging. Want to really go all out, make them assignable by the end user with an option for slow jog and fast jog. I know that the great folks at OneFinity have their number one priority on getting all the machines sent out as quickly as possible to all the customers who are currently pacing the floor and drooling in anticipation. They are right to do so, this machine is simply amazing! I think that when they get caught up, the will have more time to consider software enhancements. Till then, I’m thrilled with what I have.

Well i just got my machine and my first cut was a Wastboard flatten. TOOK 3 Hours.

We really need a feed rate Override Option. And soon.

Agreed this should be a priority feature addition!

After doing some digging last night on the web interface, there are stubs created for future implementation of this in the buildbotics layer. So at least this is not a new thought. The fields are hidden on the controller interface but there. I do feel this is a very nice feature to have. Although based on this link from their forum, may be a bit more challenging to implement https://forum.buildbotics.com/viewtopic.php?f=9&t=170&p=384&hilit=feed+rate#p384

I would love this feature. This is the one think I miss from running Carbide Motion (the only thing I miss).

I agree with all above, for large or detailed projects this is a must.

My first run of new G-code is to optimize the cut through listening to the sounds from the spindle and adjusting the feed and spindle rpm. Not having the ability to change these parameters while cutting is a real disappointment. If the feature could be added it would be an important addition to the controller.

Please hurry and build my machine to.

I feel like this feature is not likely to happen anytime soon. There is mention of it in the HTML file but it seems the way the controller works is by front loading the file and planning movements at that point. The HTML file has pretty much every G & M code for LinuxCNC in it, but a bunch are ‘Unimplemented’. I don’t think this means that the controller is capable of all of these commands in the future. So, on the fly adjustments to feed is going to be a tall task. I think it would have to be a big overhaul on how the controller runs files to make this happen.

However, I’m kind of surprised that there hasn’t been an on-the-fly speed adjustment released for spindles, that seems quite doable.
