I had this issue with the install of 2020. reseller had no fix , IT guy stumped, Mastercam Tolland couldn't fix it either, still waiting on that. No thumbnails for me anymore, imagine how frustrating this is... ( since November )

BROKE CHAIN.mcam if you open this 2020 file, It back plots fine. You will see that the arc mysteriously shortened up. (this was a good complete chain.)

2020 not dragging. on open the toolpath backplots fine (no red x's) even tho the lines are broken. after regen, toolpaths are broken/open contours. ( no edits made to any geom. only regen toolpath after open) I'm waiting for it to happen again and I'll post the file here.

One of my team has had his lines/arcs somehow getting trimmed/shortened, can't figure out how. He had all the closed pockets in the image below chained and pocketed out. when he reopened the file today the toolpaths were still there but the lines were trimmed. ( no red x ), after regen they regen to the broken chains shown below. another on my team also said it happened to him before more than once. I can't duplicate it. We are 2020 MR0. Scratching my skull atm... ( all the chains below were closed )

I don't mind having 3 separate 2D ops for T-slots. one to rough cut center, one to finish top one to finish bottom. all using unique Z depths.

Found mine in a slightly different area. go figure...

I remember a few versions ago I was able to copy my defaults.ini file to anothe pc and have all my colors / settings follow. A co-worker liked my color scheme for Cimco so of course I offered my .ini and I can't find it. Is it just me or is it not there anymore? I can not find where the Cimco Edit defaults are saved. TIA if you know where its hiding.

FOUND IT. Apparently all these items under the right click were unchecked. How ? unknown.

I have a large program 200+ ops with only 25 tools, for some reason in the toolpath manager list, under an operation's properties/tool, the list is blank. It will show small icons and large under "View" but details are completely blank. They are available in the "tool manager" on the ribbon bar. I have opened this on another seat of Mastercam here in the office, I can see the details fine. seems to be only on one seat.

I automated mine with a simple home depot outlet timer, dial it to 3 hours and go home.

if you are going with vibratory, I hope you have a spare soundproof room for it. or real good ear protection. I suggest a rotary tumbler, much more quiet and efficient IMHO, you can get multiple barrels and just swap them out so you can tumble while your guy sorts parts. plus you don't have contamination issues tumbling different jobs/materials. MSC has a 8.5 gallon for like $1200.

We bought a Shutte wu-405 couple years ago and it hasn't had a break since, ( the cost of having customs made outside outweighs the cost of the machine ) and also picked up a Walter HMC 400 that we just plugged in, haven't seen it spin yet. (these were both low hour used buys at auction that we couldn't pass up) Most of our customs are Ø.250-Ø1.00" Its nice to be able to make a Ø1.00 x 12" long EM with .300 of flute for them deep hard spots.

Recently upgraded to 2020, it converted all the nice thumbnails to a generic "2020" logo... HELP! I also tried to repoint 2018 as the “always open with” option , the icons still open with 2020. We have new systems, with Quadro P4000

Is there a hot key for the blue check button? we have bigger monitors and I'm sick of driving 35" to click it every time...
