I received a Monport GM30 (standard, not MOPA) fibre engraver yesterday, but ran into a problem because the supplied USB thumb drive decided to self destruct, meaning I don’t have access to the BslCAD.cfg and LmcPar.cfg files in the BSLAppSimple5.2.6.8700 folder on the drive, either of which I understand should ideally be imported into Lightburn when adding the Monport fibre laser.
Any advice on how to proceed would be appreciated, with apologies if this situation has already been dealt with.
I guess this was done by Windows Defender; it also detected my drive as malicious and wanted to delete the EzCad-files.
Unfortunately, mine is a GPro, so my files are not of help here. Did you contact Monport?
But you can also add the device manually, I think, by putting in all calibration values from the sticker on the machine (at least that’s the case with the MOPA).
Hello Melvin,
Thanks for your reply. As it happens things have moved at rapid pace. I’d typed a message into the Monport web site’s ‘live chat’ thingy but nothing seemed to happen - except it appears Monport did actually get the message. I received an email from them and they are being very helpful, including a link to Google Drive for all the files on the destroyed thumb drive. I am just waiting for them to let me know which machine I actually have. I believe my machine was one of two donations made to a disability charity here in the U.K. and was listed for sale on eBay. Unfortunately, the listing had conflicting information, although I did get a 5% refund, which was nice.
Hopefully I’ll be up and running very soon!!
Yes, my machine also seems different from the usual ones. The online manual states a BSL board, but mine is a JCZ one.
Let us know if you get stuck! The guide documentation we have starts here: Galvo Driver Installation - LightBurn Documentation
Hello Colin,
Thank you for your message.
I’m having to run Windows using Bootcamp on my MacBook Pro. I had success with CypressDriverInstaller and Lightburn does find my Monport as a BSLFiber laser. Monport Customer Support gave me a link to download the files that were on the corrupted thumb drive which was supplied with the machine. one of the downloads was BSLAppSimple5.2.6.0927 and within the root folder is another folder called config which contains four files including BslCad.cfg and LmcPar.cfg.
I am not really sure which of these two files I should import using the New Device Wizard. Does it actually matter?
My first try using the New Device Wizard I imported the LmcPar.cfg file but one thing I noticed in the Config Summary was that the Fiber Source Type was missing.
Anyway, I followed instructions to change the various parameters in the Lightburn Device Settings but in the Ports and Laser Settings tab > Laser Source Configuration I don’t know which is the correct ‘Fiber Type’ to select. The default is Raycus and I wonder if I should leave it as that, as I don’t believe I have a MOPA version of the Monport fiber laser.
If you attach both files here I’m happy to take a look. I’d try both of them, personally, and see what the importer picks up.
Hello Colin,
I followed your suggestion and imported the BslCad.cfg and LmcPar.cfg files one after the other and then compared the settings. Apart from the summary for the BslCad.cfg showing nothing, the only difference between the two config files is the frame speed (mm/sec) value, the BslCad.cfg value being 3000 and the LmcPar.cfg being 4000.
I guess, in that case, it doesn’t matter which cfg file I import as I still need to manually change various settings for my particular machine.
I did notice that ‘Max Speed (mm/sec)’ value is 7000 for both cfg files but the specs for my machine is shown as 10000mm/s. I wonder if I should therefore change the value in Lightburn from 7000mm/s to 10000mm/s?
Hi Nick,
That circled value is the frame speed - which you can set at-will, provided you’re within the capability of the galvo scanhead hardware itself.
Sure you can, but 10,000mm/s is a very high speed, so make sure you really need that and the laser is actually capable of this. I’d say 7,000mm/s is more than enough 
Cheers, Melvin. I’ll keep it at 7000mm/s.
