I cannot connect my computer to the Taz Pro printer. My Windows 7 does not recognize Rambo as a driver…
The drivers necessary to communicate over a USB serial connection are often installed when you install slicer software. What slicer software have you installed on your Windows 7 system?
“Support for Windows 7 ended on January 14, 2020”. You may need to find a version of your preferred slicer that was released before then to assure that any drivers supplied in that package are Windows 7 compatible.
This may create another problem because that “Windows 7 compatible” slicer version may not have support for the TAZ Pro. I’m not sure if the latest version of CuraLE will install on Windows 7 as I no longer have anything running it.
Taz pro doesn’t use a Rambo board, so you wouldn’t be using a Rambo driver for it, even if you needed a driver. It would just show up as a com port in Windows.
I am using Current Version: 3.6.37, which works fine on my Windows 7. I had been using the memory stick to load models. Now I would like to check on updating the firmware and found that the printer will not connect to my lap top.
Connect thru a com port? OK I will try that next, I certainly have not found a driver.
The com port is created by a driver installed on Windows 7. Which driver depends on the USB chip in the printer. It is possible that the chip used in the TAZ Pro wasn’t around during the Windows 7 era.
Starting at https://ohai.lulzbot.com/project/control-box-assembly/quiver/ I found https://lulzbot.com/store/archim-2-2b-pcba-retail-kit-kt-cp0155 which led me to https://reprap.org/wiki/Archim2 and https://reprap.org/wiki/Archim_v1.0#Install_Arduino_Addons.
On this last page, scroll down to:
USB Driver
Windows 10, Linux and Mac use CDC interface and have hardware driver built in.
Windows legacy can use hardware driver: File:RAMBo USBdriver.zip
This suggests that https://reprap.org/wiki/File:RAMBo_USBdriver.zip might contain the drivers you need.
