Why do most people choose to put the VFD inside the same cabinet where the controller and steppers are located? Doesn't this allow EMF to affect the electronics?
I think it comes down to cost and ease of wiring. But yes, if one does not use properly grounded shielded wires, then it might be a problem, though I've both seen and used myself non groubded wires wirh VFD right next to the stepper drivers without an issue. IMO the EMI issue meme has grown to be much of a bigger issue in online discussions than it actually is in practice. In most setups the location of the inverter is not the actual issue.
Awesome video, just silence. Although some on-screen description would've been great, by any chance, can you share the yml configuration file since im building printnc with a very similar setup, fluidnc on mks tinybee and cncjs
did that cooling system actually work? PC systems only typically deal with like 75-100W at full load, I'm sure a 2.2kW spindle is pushing it to the limits. You would benefit tremendously by just increasing the size of your reservoir to a 10-20L bucket, that gives a much bigger heat capacity
I previously had a 20L bucket with a 230V water pump. Haven't noticed a difference with this setup. Tho as a disclaimer I have to say that I am just a hobbyist and the machine does not get pushed to its limits or used very often/long.
@@kyy-_- CPUs will generate much more heat per watt than something like a spindle. The setup looks quite nice for a DIY hobbyist although the rad being so close to the spindle doesn't look the like the best idea since it will get full of particulates.
In terms of component ventilation, you've neglected everything you could! As for electromagnetic compatibility, you haven't taken care of it either. A plastic cabinet is a bad idea, you'll understand with time.
@@kyy-_- You can joke. I have been repairing machine tools for 8 years. The way you installed the frequency converter indicates that you did not look at the installation manual or you think that what is written there was written by fools!!
It's just common PC water cooling parts controlled with the VFD's DRV port so the fan and pump is only on when the spinde is actually running. If you've got the regular chinese 2,2kw spindle you'll want to upgrade the ports to M8x1 to 10mm in order to use 10mm ID hose instead of the standard 6mm hose.
