im not too sure as of yet which firmware im running but whatever you have on your display on your printer seems to be waaaay advanced than the one on mine hahaha. will check soon and get back to you
Joe, they are probably close to the same. I would think you might have a later version, last time I spoke with Ada they were using R8. Mine is R7. You opened the Marlin file and went to the configuration.h tab? Have you mounted your extruders together or spread them apart? Unless you plan on using dual extruders, you can just remove the second extruder. Then it wouldn’t interfere and you wouldn’t have to worry about changing the travel limit. I would still reload my firmware to original settings.
im actually emailing back and forth with her right now. about to run the bl touch test. ill pull the sd card after im done to see what firmware im on
Ada is really very good. I go to her when I have problems. She always answer’s and helps. It’s kind of annoying sometimes, they will answer only one question at a time no matter how many emails it takes. but they really know their stuff. One night I had a Skype session with them that lasted almost all night long. They actually watched my machine operate over a video chat, and figured out what was wrong.
wow, that’s awesome that they watched it for that long. I completely understand what you’re saying about the one question hahaha. if you ask two questions in one email you can pretty much save one of those questions for the next email.
Yes you have to be patient but they will isolate and solve the problems one at a time. I think it was two months before I got a successful print out of my machine. Another good recourse is Tamas’ Palagi from 3D hubs. He is also on this community. He skyped with me one weekend, I gave him control of my computer and he pretty much taught me how to set the Z offset, upgrade my firmware, Helped me learn to control the printer with G-code through Proteface. He helped with lots of stuff. For free! I’m afraid I might have leaned on him a little too much. He was excellent, but tends to take liberties with your machine. I would stick with Ada for now.
hmmm just took a look at my SD card and seems like the firmware isnt on here
Really? You need that! Should be a folder called Marlin Firmware. If not have Ada forward it.

So crazy stuff happening to your printer Joe? Sorry it took me forever al these replys went to my junk folder and today I decided to jump on here to check somwthing out and saw abunch of replys. So Joe do you have the trex 2 or the trex 2+? If you just have the trex 2 then its either a faulty x axis home button or firmware issues. If you have a 2+ then its different all around. I dont know how it actually works but you basically have 2 extrudes on looks like 2 x axis belts or does it use 1 belt?. Im sure there is 2 x axis homes. #2 extruder probably has a different home like xb or something. Im not sure. But ill take a look at simplfy and see if it has it. I heard for a long time that simplfy didnt habe it set up for dual extruder until recent like a year ago. So with the 2+ im sure its confused because no other machine out there has the trex 2+ setup.
Hey, I have a T-Rex 2+. Im just so lost and wish there was a tech of some sort to figure all this mess out hahaha.

Yea I wished the same thing. I dont know how the new one is but when I got mine just regular trex 2 I had problems with reverse wiring. Fans not probably attached. You kind of have to unplug it and double check everything. I had my control box fan hooked up backwards and it fryed the fan. They used hotglue gun to glue connector together and it was backwards. So just double check everything. There should be a + - on the circuit board and if not get a volt meter to check. Would need to plug it in at that point. I wish I could be more help. I do like the new style though. The regular seemed like a half ass design to tell you the trueth. But it does the job. Once you figure everything out its not a bad printer, its actually decent prints. But meep in mind if you cant i would suggest sending it back before the warranty is void. Best of luck to you.
How long is the warranty? Think my company also dumped the box it came in too. The design is simpler but the instructions and customer service/tech support is a little shaky. Really should be a plug and play kind of deal. Our company has another printer (makergear 2) and its working like a dream after 3 years. we only got this trex to make more prints on a bed
Hello there, I’m new to this forum and was looking for informations about this TRex2. I will place a comment here just to share my one year experience with this machine which is my very first printer.
So, if it can help, when printing with dual extruders in order to clone the object and have them spaced up to 20cm, it’s not necessary to adjust the setiings in the firmware. This can be adjusted directly in the preference tab of Cura : printer settings -> only the width has to be adjusted from 400mm to 200mm… and its ready to go. One last very important thing: when the second extruder is tighten on the belt, no leveling process should be done at this time (the second extruder would hit the limits of the X axis)… and ensure erasing the G29 line in the gcode directly in Cura, so that the printing process wont start automatically by levelling the bed as it does by default.
I’m also here bacause of an issue with the printer i really don’t know how to solve. It seems that Ada and the formbot team didn’t find any solution for me… yet (hope!!!) : my printer just can’t print now as it can NOT go on -Z axis. It’ si isn’t a problem with the BL sensor which is away from the bed, it isn’t a poblem with the firmware as i re-uploaded the original to have a try… here are the symptoms : when hitting “home”, the extruder travels to homeX, and the bed to HomeY… then the extruder goes to the middle of the bed : then (the problems starts here) : instead of going down, it goes up a bit then stops. When leveling the bed, the head keeps going up instead of going down at every corner and the middle of the bed. One more thing, the -Z move controler doesnt work at this time. This used to happen to me some weeks ago, but after a few restarts, it all went back to normal… unfortnately not this time. Ideas to solve this problems would be of course highly appreciated! thx
Hello, i know this thread is a little old. but a friend recently got one of these forbot printers. i didn’t see the firmware files on the sd card. and i don’t currently have access to it. i helped him get the printer up and running. and i can tell you guys, the bias voltage that sets the current on the alegra drivers is usually pre set by the driver manufacturer for around an amp on 12v. the t-rex is 24v and the drives in my friends printer ended up being set way too high as a result. this can damage the drives and is likely the cause of the skipping some of you are experiencing. the alegra drives are probably not the best for such a heavy y axis. i swapped the drives for texas instruments 8825 drives and set the bias to a safe level. (basically something under 2 amps, more like 1.5 amps, but the amps aren’t actually that important) make sure the motors aren’t burning hot and that the chips themselves stay out of thermal protection. motors can usually take more than they are rated for. the drives are more sensitive. ti drives do better over 1 amp than alegra drives.
now on to what i need. the printer doesn’t seem to want to communicate with any host software other than cura and the temperature control is unstable bouncing in a 5-10 degree range but i can’t seem to correct it with the pid loop settings. i would like to compile the latest marlin to fix these issues. i haven’t found pid auto tune to give the best results, i prefer to use repetier or printrun to monitor the temp and pwm while i manually tune it. if anyone can share their firmware folder or at least there configuration.h it would be a big help. there is no formbot v1.0 in the boards.h file. i’ll need a good configuration.h to copy setting from for a good firmware for it without tracing all the connections.
Hi, so my temperature holds very tight. Now I can share my firmware files, but I have the Formbot T-Rex 2. I have learned there is a Formbot T-Rex 2 + and the firmware will not be the same. Do you want the T-Rex 2 firmware?
that might give me a hint, especially if you have the same main board. if you can look at the board (remove the cover it likely has fans in it) if the silk screen reads formbot v1.0 then i should be able to work with it.
i do believe its a trex 2+. it appears that the t-rex 2 has a touch screen with color graphics while the plus oddly has a “reprap discount full graphics smart controller”, but that doesn’t rule out main boards being the same.
My understanding was the 2+ has a separate X axis for the 2nd extruder. At least that was the understanding I got from the conversations on this forum. If that is true the firmware will be much different, but I can certainly share what I have. I see I cannot attach the folder here. Is there an Email I can send it to?
Also the only silk screen writing on my board is MKS GEN V1.4
ah… yeah. i like that board, it’s cheap but much better made and better looking than the ramps but i don’t know if it helps me… i’ll just contact formbot but thanks for taking the time.
the other differences are all in the configuration.h dual x axis in now native in marlin. it’s just a matter of uncommenting the correct settings. i’d be able to figure it out if the main boards weren’t different. but since they are not the same i’d be taking a risk using the wrong pins layout. there is a good chance they are using the ramps 1.4 pin layout like many other boards do. but i can’t be certain. thanks again for the quick replies though.
OK no problem. I am only familiar with the one printer. It is the first one I’ve owned and haven’t had it that long. I would help if I could
