You seem to know your way around these PORTconfig:ADVANCED manipulations & changing designations (don't worry about manually assigning a ComPort that's already in use, as a reboot will get Windows to realign the whole hardware shebang and allow you to use Com3 if you want). I personally prefer the SignBlazer program, and although I work inside the VM workspace sometimes, it's SBE as a rule, and I've been doing so since first getting into this game with my first USCUTTER machine and an actual SB install disc!

What version of WindowsOS? This is for sure related to COM PORT designations and configuration. It's beyond my pay grade to proceed further. Drop back in here to let us know if you sort it out.

You can try approaching the District Manager of your local Highway Dep't. They have parking-sign blanks, and maybe you can get them to sell you a stack?

We're back to the PORTS again, in the Device Manager. There should be a VCP STM32 listed (assuming you have Win 7 or 8 or below -- Starting from Windows® 10, the STM32 driver is not applicable for use).

eBay?

The VCP connection should be listed under PORTS, not USB. You asked to get this LP working on VinylMaster, I believe that my method will work. (The fact that SignBlazer manages to function with the assigned USB Port7 is indeed interesting, but irrelevant to the subject of this thread, which is an attempt to migrate away from SBE and start using VM for both machines).

CoreArt, whazzup? First of all, as far as we know, SignBlazer supports Com ports 1-4 only so how are you successfully using COM7? Interesting to see that configuration in SBE (screenshot). Check this little item out -- it creates a Virtual Com Port, (STM32) and that should allow VM to just see the LP using that. https://quadmeup.com/stm32-virtualcomport-driver-for-windows

Fortunately for you, it's a very basic Serif block font. And remember, the grass is always greener...where the cows roam. Y-W

Lubalin Bold (Standard installed font with SBE) Rockwell Bold is also in the same ballpark. Here's a bit of grass if you need some.

Since you're essentially a hobbyist, the MH871 is fine. They even are selling a refurb unit, for only $340, and knowing how USCUTTER stands behind their warranties, that can be a great deal for a guy like you. [[[ EDIT TO ADD: I just noticed that on the USCUTTER webpage for MH 34" (model 871) they're offering the $340 price for a NEW unit as well, which is strange to see that a refurb and new are equal in cost, but such is the manner of management, such that they have their own unique marketing methods! ]]] I operated an MH871 for several years in a retail setting, while noticing it does tend to track kinda poorly over long distances (like 12-15 feet) but you aren't in a banner-production mode anyway.

The SignBlazer program uses RedSail machine driver to run the MH. (And Liyu to run the SC2). Honestly, I would be shocked if the MH100 now being sold isn't compatible with RedSail, or perhaps Copam or Roland. USCUTTER isn't any longer supporting SBE, obviously, so they can't run that test for you. When you say "a Lot of files..." how many are we talking about being used regularly? If it's just on occasion, then EXPORT the specific graphic you require and IMPORT to VM, which is the default program provided along with the new cutters. Also, the price difference between the new Mh100 and the old MH is about $100, which is probably worth spending to get a better upgraded unit than the outdated MH. We've not had anyone review it here, so cannot reference a user who's noted the advantages or relative quality. That being said, I'm fairly certain you won't have issues with being an adopter.

Please put in a ticket to Future Corp. (producer of the VM software) This is an issue only they can resolve. (by adding new machine drivers to their program) Honestly, I would venture a guess that the regular MH drivers will work on these updated units. (I've run older MH cutters over the years with RedSail drivers).

You really should make a dial that goes up to 11. This is Spinal Tap-the movie reference

The numbers you typed are Sans-Serif typeface and the ones in your original part (as pictured) are Serif font. Not a critical matter, of course, but just thought I would mention it to a newbie.

NOTE to CHASE: This is not in reference to the VCP Driver which was offered by me above. That little Virtual Com Port item is a stand-alone bit of code, which provides you with a Device Driver for USB that appears on the drop-down list of connections, and allows communication with the cutter's USB chipset (Serial Emulation).
