This is what out re-seller has instructed us to do in the past. Mastercam issue seems to be affecting windows and creating the devices and printer disappearing issue. Will update if we get any more information on this on why. It does seem that the only common thing between the machines affected are that they had copied my mcam folders.

The issue is (well was now) mastercam wont even start at all. Currently has turned into a whole other issue now. Devices and Printers wont load what so ever. Have uninstalled all versions of mcam and cleaned out all documents/reg/files. Still nothing on the devices and printer issue. The config file being copied kind of throw up a flag because when we install new vesions of mcam typicalled we have the same settings from PC to PC. So I or who ever sets/installs mcam we copy of a set of mymcam2018/sharedmcam2018 folders into correct locations after install so settings stay standard throughout the shop. This may or may not have been why we were having the mcam issue. Now unfortunatly were having the devices and printers issue with windows.

Attached are specs of my PC. According to our our tech guy in house he says that the "devices and printers" are not even available to access. Having issues with the service Print Spooler. Not sure if they may be related or not. Verified that all of our video card, printer drivers are up to date. He was here for 3 hours after hours trying to get the PC to run Mcam and was unable to. We have been running MCAM on most of these machines for years with no issue until version 2018. Again not sure if that is related or not just trying to come up with a solution.

First post! Hello Folks! Amateur programmer here only using mastercam for about 3 years now. A lot of the older guys like to have me do all the research on issues with their software. Let me get straight to the point. We have about 8/9 PCs around the shop running mcam, and 5 of which are full time including myself. Recently with the install with 2018 being released I installed it on all of our machines. Some programmers are not so quick to jump into the new release as others. Myself, I jumped right in. I encountered an issue with printing from and through phone calls back and forth, sessions with our re seller we were unable to come up with a solution or reason for the issue. Basically it would only print the top maybe 10% of the page and cut off the rest. Long story short I just resulted to printing to a PDF and then printing from there. Short work around, but work around none the less. I was the only one having the issue until a second machine started having the same issue. After some use and a few weeks went by one of our machines had encountered an issue where we would open MCAM 2018 and nothing would happen. No splash screen, nothing. Yet after some investigation opening the task manager mastercam would still show up in processes but nothing would be open. After working with our reseller and going back and forth with them attempting to fix the issue for days they were unable to figure out the issue or why this was happening. The reseller even got CNC Software involved and they couldnt figure it out. Our short term solution was to choose a system restore point previous to the issue. It has since happened three other times. Once more with the same machine and twice on another. Now this time the system restore point has not worked. These are just happening at random times upon closing/opening or on restart. Wanted to post here to maybe see if anyone else is having similar issue or may have suggests of us. Much appreciated! Sam
