EMC filters generally include Y caps between each phase and ground - these are particularly effective for dealing with high frequency common mode noise. These form a capacitive divider, so if the ground connection isn't made, the case will be held between the phase voltages. You don't need a high im...

Could do with more info. What supply voltage are you using? Some photos would help. What is this filter? If you leave the filter ground floating you'd expect the case to measure somewhere between the live and neutral voltages. Neutral is usually near ground potential unless you are running between t...

I got an email reply from him on 6th Oct - said he was having a busy time. My first email didn't arrive with him, so most likely you had a similar spam filter issue.

These Chinese VFDs always seem to skip over any requirement for an EMC filter on the AC input, yet they are not magically able to avoid generating significant switching noise during operation. As a matter of good practice, VFDs should be fitted with a decent quality filter, rather than try to figure...

The mechanical click is caused by a spring and detent somewhere inside the MPG encoder handwheel. If you are a bit of a sportsman and don't mind potentially voiding the warranty, you could try to take it apart and remove the spring. It won't alter the resolution but would give you the "smooth&q...

Adjusting the cutter comp and setting backlash values is one way to frig the results but ultimately minimising mechanical backlash in the mechanism should always be your first step. I'd recommend you use Swissi's Probe App to tell you what your mechanism is capable of. As Uwe says, careful setup and...

I'm not familiar with Stepperonline products but they seem to offer 2 VFDs (H100, B600). The H100 seems to be less expensive and comes with STO. Would that be a simpler solution? https://www.omc-stepperonline.com/download/H1_Series_Inverter_Full_User_Manual.pdf https://www.omc-stepperonline.com/h100...

I have worked in the automotive for several decades. Engine coolant is almost invariably water glycol in the ratio 50:50 or very close. It's perfectly suitable for use in all engines with cast iron, steel, aluminum, whatever. The different colourants and descriptions ("racing") are of no s...

On one of my Acorn systems I have a pre-owned Lenovo M700 mini PC, on the other I have a Chinesium NUC clone https://www.gmktec.com/products/amd-ryzen%E2%84%A2-5-5600u-mini-pc-nucbox-9 . They cost about the same but the NucBox 9 is more powerful and comes with W11 Pro. I can't say it's been formally...

For when I use my 4th axis, I have disabled the 4th axis homing in the .HOM file, otherwise it will sit spinning forever. As Keith says, you can set home manually.
