So my adventure with Onefinity began quite recently when I figured out that I needed to be able to carve some curved doors from 1" MDF. In the last 3 weeks I picked up a basically unused Foreman, carved the doors, figured out how to make 1 piece and 2 piece doors, made some custom fluted panels, learned the basics of Maker, used AI to build a custom app to import a list of door sizes and create nested vectors to import into Maker, and generally have been fully immersed in using this CNC. It’s a fantastic machine and I wish I’d gotten it sooner.
During this time I was making speed change settings for toolpaths but didn’t clue in that the speed was not changing. I have the Masso controller and I assumed a Redline spindle but I’ve learned that it’s actually an aftermarket unit that Sola Fide Designs supplied. They do not appear to supply this any more and only offer accessories for sale on their website.
I’ve spent a few hours trying to find documentation for the VFD and spindle and so far cannot. I’ve sent a request to Sola Fide and hope that they will respond. In the mean time I’ve got some carving I need to do and was hoping that someone else has the setup details for this same unit. I can’t figure out what actual brand the spindle is but it is 220V and is controlled by a DURAPulse GS20 VFD.
If anyone has any suggestions for how the Masso needs to be configured or the VFD configuration details I would greatly appreciate you sharing that info.
I may have just discovered the answer to my question… It appears that the VFD will not let the spindle go below 12,000 RPM. It WILL however, allow it to go faster. I was able to use the MDI screen and set the speed to 15,000 and heard the pitch go up and saw the VFD display go higher as well. I will investigate further to see if this is a limitation of the VFD or a setting that can be adjusted. Some of the tools that I am using do not need to spin at 12,000.
I too have a Sola Fide Designs spindle kit. Mine uses the CNCDepot 2.2Kw spindle with a ISO-30 tool holder and ATC.
To my knowledge there were only a few of my model made. It was definitely a high-end solution that came with an industrial price. But well worth the money in my opinion. The machine has yet to be a limiting factor… ok not gonna do steels, that outclasses the machine.
Nick is a good guy and will take care of you.
Spindles usually have an RPM band. Take Haas machine the big boys … the spindle I used maxed out at 6k RPM. My spindle max’s out at 18k. All of these spindles lose horsepower as the drop in RPM. So, a limit of 12K is pretty reasonable … though for true drilling CNCDepot says you can go lower.
I would suggest some education in the area of “speeds and feeds” … you can almost always come up with a good solution.
