Hi,
I recently bought a Laser Module Kit for using it as an additional tool on my Ender 3 S1. But over the time I got tired of constantly switching the two tools. Is there a way to get the Gantry of the Falcon system without the Laser and/or the controlbox which come with the Laser Module Kit?
Thanks in advance 
Get a used Ender (does not need to be the S1, any Ender 3 will do for that purpose). You can get some for 30$ or € already.
Is there also one with the size of the Falcon gantry?
That would be 400mm, you could look for an CR-10 S4 (quite old so don’t spend much on it, maybe you can find one used, but it’s 400mm) since the laser module has the same drivers for the stepper motors it should work with that as well, not sure if the connectors are all the same for the end stops but you can make it work if you are willing to tinker a bit.
