OK, I'll attempt to be a good boy here. Right now I'm very torqued at the whole carvewright LHR experience. My machine is an early A model machine. I bought it in 2007 from Sears as a compucarve. I finally got tired of trying to keep it going and sent it into LHR for the full upgrade to carve tight and the heavy duty belts.
First project out of the box and I broke a bit. I was cutting 1/2 aspen with it. Snapped the bit off... dug it's little self into the shiny new belts and broke the teeth on the small X-Drive gear. So, I ordered a new X drive gear train as you can't just buy the gear anymore. Got that in... cleaned the machine thoroughly put everything back together and I had all kinds of problems... board sensor problems... tracking sensor problems... board error problems, etc... I did all the sensor checks and all was well. Compression rollers showed released when no pressure and compressed with pressure... board sensor shows 152 on a nice piece of red oak... tracking sensor shows movement when using an old straight edge wooden level and sliding it across. So, I threw another board in that was a 2X4... seems to work... the problem was that evidently you can't have anything even close to 1/2 inch (It measured .515 inches on my micrometer). So, off to the store... get a piece of .75 oak... square it up nicely... run the first project.... Check tracking rollers... checked no problems.... clear board sensor... blew low pressure air on the glass... check with the sensor check menu and it reads 153 with my red oak... doesn't seem to be any problem... press enter and I get simply "board"... then nothing... press enter... "Board problem" So, I'm at my wits end with this one. Finally, I got an error code of 03-400
This machine has 89 hours on the cut motor... 97 hours "servoing"... very low hour machine with chronic problems... Anybody need a really nice boat anchor? If there was anything such as a lemon of carvewright machines, I've got it! Unfortunately LHR is not real good at answering e-mails and I work a day job that prevents me from calling with the machine in front of me to get help.
