    Trotec Firmware Downgrade SOLVED

    Hi Sawmill Creek,


    LONG STORY (skip to below for firmware downgrade instructions)
    I thought I would write this article to help people for the future. I have an old Speedy II unit, basically a 2003 Speedy 300, its the same thing but I guess some of the components are older but 95% of the machine is the same. Apparently this 5% of difference extends to firmware and something is different in the motherboard and/or the motors, the CPU boards are the same (verified)(top circuit board for motor) and im pretty sure, but not certain, that the print boards (bottom circuit board for motor) are the same too. Anyways I have been dumb and thought that this machine was a serial only machine for nearly 8 months and have been thinking of upgrading the motherboard to get USB. Well after this work looking at getting a new motherboard, I bought another laser that was suppose to be for parts (it had the new motherboard) and went to transplant and found that the Speedy II unit has USB, but there was no cutout on the back. So easy work for my jigsaw and I opened up a spot on the back for the USB and I feel like an idiot. I was actually pleasantly surprised that the parts unit was in very very good condition, so now I'm refurbishing that. So the whole point of wanting USB was because Trotec said that Job Control 10 was the highest software available to serial only units and that software would no longer be supported for this. So I find the USB, and got a copy of Job Control 11 online at Trotec and upgraded as I was excited for the new features of JC 11. As with every JC update there are firmware updates, I update the firmware on everything and call it a day. Well when going to cut something, the machine was not firing the laser and after about 10 seconds I would get a "firmware x-axis tracking" error. So apparently I'm probably out of luck on JC11 and am happy I didn't pay the $1900 for the updated motherboard as I doubt that would have allowed me to upgrade to JC11 anyways. So new problem, did this firmware update just turn my Speedy II into a very big and heavy paperweight? I will say I wrote in to Trotec on a Saturday about which firmware was proper, but really asking if it was Speedy 300 BL or Speedy 300, I didn't know what the BL was or not but after a little research I found thats a newer motor. Trotec did respond on Monday and say, you can't upgrade the firmware of the Speedy II unit to at least 11.0.4, as there are firmware errors. I have been told by Trotec multiple times that firmware cannot be downgraded once its been upgraded. I have an enormous amount of experience in firmware updates across many many many circuit boards, computers, whatever you name it. I have seen where companies lock firmware downgrades and just assumed when Trotec said that it couldn't be done they were right... long story short they are wrong and their firmware can in fact be downgraded and if anyone else gets in this situation ill explain below how to do it. I thought this would be valuable as I was the equivalent of biting my nails the whole time during downgrade as I had an ok chance of "bricking" each item needing a firmware downgrade, and I can report that I would not sweat to do it on subsequent machines now that I know it worked successfully. Verified full downgrade from 11.0.4 to 10.36.5 on each firmware holding board of a Speedy II, including Rotary. Anyways, I hope it helps someone.


    Firmware Downgrade Instructions:
    Prerequisites: The file for the firmware for your machine in the version you want. Your Job Control installer (USB, CD, Download) has the corresponding version in "_Firmware" directory in the root. (its easy for anyone to find) If you need a specific version ask Trotec, if you do not have it.
    1. Open Job Control (Most any version should work)
    2. Connect the Machine to JC
    3. If the firmware doesn't match the machine, it will have a popup, just click no or cancel or whatever that gets out of it.
    4. Click "Settings" at the top, then click "Update Firmware" (this is a separate application, even though it will look like its part of JC)
    5. Under the "Load" part, select your file (mentioned in prerequisites), it MUST match your machine type, but whatever version should be acceptable.
    6. Make sure the machine is connected
    7. Verify that there are no errors and only warnings along the lines of, the current firmware is XX.XX.XX and the proposed firmware is lower XX.XX.XX do you wish to downgrade.
    8. Press "Send", if you are not on a dedicated circuit make sure nobody messes with anything that could disrupt power. MAKE SURE POWER WILL NOT BE DISRUPTED OR YOU WILL HAVE AN EXPENSIVE PROBLEM.

    Thanks for the write-up. I've been scared to death to upgrade mine due to known issues.
    120w Trotec Speedy 400 with rotary and cutting grid table. And now acquiring an endless collection of woodworking tools.

    Depending on what model year your 400 is you either have analog or digital servos. I think they transitioned in 2018 to digital. If you have optimotion 360 thatís the digital servos and I do not know nor have I tested upgrading/downgrading those but the analogs like what I have worked fine. I would suspect the digital ones would too but canít promise it. Keep in mind I was upgrading a 2003 unit though to modern current software and it works great! I can say Ruby is a game changer and if you havenít upgraded you should. Thereís some quirks and I did a brief write up about those but if you need a new laser operator that doesnít have past experience Ruby makes it pretty easy.

    That did not help me out. I might be doing something wrong. Can you help me out?
    I have Trotec II 80W and I live in Finland <- I told you that so you know that I'm not able to visit trotec suplier in our country.
    1. I upgraded my Jobcontrol to 14.4.4 and then it said to upgrade also the Firmware so I chose the one I felt to be right from the list, It was Speedy300-8011_Firmware_11_04_00_01.tuz because there was no Speedy II option and those machines are quite the same. NOW I have a problem. I cannot downgrade or do anything with my laser. Any ideas how I may proceed?

    Old Firmware is SP2_8007_Firmware_10_07.tuz but I'm not able to send it back to machine, it only say

    Error: Invalid Version in Tuz-File (10.07)
    Warning: Downgrade of Cpu from 11.04.00.01 to 10.07
    Warning: Model numbers of update and device do not match
    Warning: Downgrade of DspX from 11.04.00.00 to 10.07
    Warning: Downgrade of DspY from 11.04.00.00 to 10.07
    Warning: Downgrade of DspZ from 11.04.00.00 to 10.07
    Warning: Downgrade of DspL from 11.04.00.00 to 10.07
    Error: Firmware is deprecated, use current firmware

    I have sent this also to Trotec technical support. But this your instruction is very interesting. However it did not work for me or I did something wrong though I followed your instructions as it says above
    I have downgraded JC back to 10.1.0 -> no work
    I have downgraded JC to 7.something that worked only with XP PC -> no work
    I have downgraded JC to 6.something -> no work
    And finally I'm back with JC 10.1.0 and I have tried downgrading without succeed
    Have you any idea how I may proceed to get machine back working?
    I don't want to put it into fishing net weight....

    I think you may have chosen the wrong firmware file. It should not be bricked. Are you connected via usb or serial?

  6. I'm connected via usb

  7. Oh. Did you mean the engraver? It has serial connection and usb in laptop - that way it is ccobbected

    Just a note, and not a pleasant one--

    I don't have any Trotec anything, but I DO have lots of Gravograph equipment, and both are mfr'd in the same part of the world, which may or may not mean much, BUT-

    Some years back I bought my Gravograph IS-400 rotary engraver, which came with a "Discovery" version of GravoStyle7, 'Discovery' meaning it's a bare-bones program that works well for sign engraving but devoid of many nice graphics editing features. But it DID come with new software and firmware for Gravograph laser engravers. While I couldn't get the new firmware to load, I DID try out some of the new basic-program's features, like engraving bottom-up, one-direction engraving, and much higher resolution (up to 3600 line/dots per inch v 1200)--

    What happened when I tried to run a job with the new software, the machine went into a combination of doing-nothing or ludicrous-speed X-axis travel set to east-coast coordinates with no coming back- you'd have thought I was taking a jack-hammer to the thing...

    Ok, so that didn't work, back to the old program, no problem...

    Except-- My little foray into unknown machine-control territory fried something in the controller. To this day it won't accept ANY firmware changes. And the worst part: IF I happen to load an engraving job from Laserstyle, and IF that job has ANY vector path instructions, whether I turn off vector cutting or not, the main driver becomes corrupted, and the machine refuses to work correctly, at times doing the east-coast-jackhammer dance. The ODD thing is, the Laserstyle driver used by Corel works just fine, any jobs sent via Corel work just fine. But if/when I send any vector info to the machine from Laserstyle, then ONLY raster jobs will work via Corel afterwards, and any jobs with vector cutting cause the machine to either jackhammer the right side of the cabinet, or the X-axis will crawl about 1 inch per minute, WITH the laser firing sometimes. The fix is to unload then reload the Gravo driver, then all's well with Corel. SO, to this day I can't use Gravograph software to engrave. A repair to the controller is about a $1300 job, and since it works fine with Corel, I've just avoided sending jobs via Laserstyle. I still USE Laserstyle for some graphics creations & such, but they get changed to DXF files I can use in Corel.

    My point, and the not-pleasant part, is that I'm afraid it's entirely possible that the new firmware upload may have compromised something in, or to do with, the controller. All I did was use the new software...
    ========================================
    ELEVEN - rotary cutter tool machines
    FOUR - CO2 lasers
    THREE- make that FOUR now - fiber lasers
    ONE - vinyl cutter
    CASmate, Corel, Gravostyle

    I was recently on multiple hour plus long calls with one of the Trotec support people I know is good, we had talked about firmware. He had mentioned that he has recovered boards that he accidental put the wrong firmware on by redoing the process. I am certain there are two different speedy 300 firmwares maybe more. I know one is for the older (including speedy ii) that has analog boards and silver servos and another that I think is listed as BL that is for the newer (2017+ I think) digital servos with black servos.

    Iím not at a good point to review the firmwares, however I think itís 8011 speedy 300. Itís been a minute since I did it but whatís coming to my mind as something wrong is why is the CPU firmware newer than the boards? I donít think you can change major versions but I think you can downgrade to v11 firmware. Check your ini file and maybe shoot an email to Trotec. Iíd attempt modifying the ini file so that it thinks itís a speedy 300 vs speedy ii. Keep in mind that 0 counts so if a speedy 300 is number 5 on the list you input 4 (because 0 counts)
