Tell us about yourself!
And you get free energy for your stove ?
I also use a CPAP machine and I run it on tap water. I presume you live in a hard water area. You can buy de-ionised water cheaper than distilling your own and that is as good as distilled for a CPAP.
If you have a long driver bit, you can put it directly in your drill, which holds it firmer to get a centred point.
Using a laptop is not ideal as there are issues with power saving and parallel ports. Mach 3 takes over the control of the port to keep correct timings and power saving can mess this up. Just use a normal PC. I use a card for the LPT and it is fine, once you get the driver correctly installed.
Would you feel the same about the mosquitos that carry Ziko ?
