it was a bit difficult gluing the roof because of how thin the wood parts are but other than that it was straight forward

hi the extrusion i used was 2040 with 6mm slots i also changed my lead screws to single start

yes i understand where your coming from i have enclosed a shot of the alloy extrusion i got for mine i also replaced the lead screws with single start for better accuracy i think i have gone as far as i can with this machine now the only thing i might do is add extra steel runners on the bed that might help stabilise it more

the problem with extending the x-axis to 400mm plus especially if your intending to use the bigger motor as i have is the torsion when the z-axis moves down to the cut and moves along your design the steel guides tend to move back and forth so you to adjust your cut depth to lessen this and would mean your project would take longer to complete ive added a couple of images of mine you can see the size change in the y-axis and the dust from working with slate

basically it just means that i can get the full 200 mm rather than just 180mm extending too far would create more problems i have already upgraded the motor to the bigger 500 w one but because of the method i used it in its self has also created problems for me solve i will add some pictures when i have a bit more time
