Hey ya’ll, first off thanks for all of the awesome people in this group providing support for the k40 community! I’ve been lurking for a while, I run Epilogs for a day job and took the plunge into the k40 a few months ago.
My machine arrived in good condition, I made a DIY Z- table etc. and I can cut and engrave just fine. I do however, have a question about the k40 that I haven’t seen asked yet. The right side of my X-axis arm is attached to the belt of my Y-axis via a screw, this screw also holds the Y- axis belt together… Is this normal for a k40? I ask because my X-axis arm sags on the right side and I fear if I tension the Y belt enough to level it, the belt will break and if I don’t level it, alignment will be damn near impossible.
Again, thank you all for the shared knowledge and for your input.
Well on the right of the x-axis arm the bracket does attach to the belt with a screw. There should also be a roller attached to the middle of the bracket that runs along a channel in the side of the bed frame
You say the belt sags on the right side? Are you sure you aren’t actually referring to the y the foward and back motion is the y the left and right motion is the X… The y axis belt tensioners are the two holes in the rear of the machine a few inches below the tube cover they are around a 3/8-1/2 inch size hole
I’ve tensioned the Y-belts, the problem I’m having is that the entire X-axis arm drops on is off level because its weight is only supported by the Y-belt on the right hand side. @Nedman my bracket does have the roller attached but there is no channel on the gantry for it. I think this is why my X-axis arm is slanting on the right, the weight of the arm is only supported by the Y-belt that it is screwed to.
@Nedman The first one is similar to the photo you posted. The second is looking through the access hole towards the gantry where I’m assuming this little channel for the roller should exist…
