I am a complete noob at casting. I am looking at the China Jewelery foundry to use with my 3d printer and investment cast parts for my CNC machines.

Can someone tell me the approximate weight of...

It's done except for the cable carrier and fine tuning. Picture is my boy on the table vacuuming it off after machining plywood.

More progress today.

Drilling and tapping set screws for the rack and pinion drive gears.
Installing power supply

Other lessons learned, to get good smooth angle bar guides, I found a device that converts a angle grinder into a sort of mini chop saw. I used parts from that, roller bearings and 3d printed parts...

This is my second big DIY machine and my 12th router build.

I had that issue with a all in one China board. Turns out it was a defective board. They are a $38 item from China so when that issue pops up, I just get another board

Why is still a sticky thread?

However after using it on a couple of my DIY plywood machines for about a year, I was finding that the angle bar was not really good to hold the...

these are showing 92 ohms for the 800 watt heaters.

I have a 1.5kw air cooled china inverter spindle. SO far works great except that I really would like a spindle brake on it when I hit the emergency stop.

I see where they say there is a resistor...

I have been using palm oil as cutting oil for drilling. I am looking at experimenting with a soap, water, weg oil mix and rice bran oil. Ricebran oil is 490f smoke point.

I have zero problems with USB and plasma. I use a hypertherm no high frequency start. Torchmate table. Super reliable

Lol. I'm going to the metal fabricators convention this week. I'll prob see something like that. I could slap the brand name Kondia on it.. Lol
