Hi guys,

I have a small wooden work shop which is well insulated. I have my cnc router and pc in there. The temp inside was 5C (outside -2C). I put the heater on and the temp rose to about 11C. I started cutting shapes out of 18mm mdf. I do this in 3 passes x 6mm. I noticed that the 1st pass seemed okay but the 2nd pass was not quite following the same path as the 1st pass and the 3rd pass was different again from 1st and 2nd.
I bought the machine in April this year and have had no issues at all. The last time I cut prior to tonight was last weekend (wasn't as cold) and had no problems. I wondered if the temp had something to do with it. I have had to bring the pc into the house when I am not using it as I found out the operating temp is +10C. If not the temp is it something else?

cheers Steven
