I was joking about throwing it out but i was pretty frustrated.
I definitely would never start a program and drive off somewhere or go to sleep when working with wood.
I’m usually close enough to hear the machine running if I do leave to go to the bathroom or kitchen.
The first pic is last 2 failures do to wobble and one decent one which was the 4th attempt the rest didn’t go so well.
1st one is just awful… it wobbled so much.
2nd one started fine in the lower right corner. the move towards the top and went deeper and wobbled.
3rd is best I have so far, but I’d like to to be a little deeper so the rest of my attempts ended in failure so far. I probably didn’t wobble on this one due to the fact it wasn’t cutting much material.
i need at least 2 of these to be good…
feed rate is 100mm/m, spindle speed is unknown. any faster on feed rate and the wobble is exponentially worse.
the second pic is all my scrap except the 2 already shown above.
1st was my bad the tool was loose. it wobbled and flew out…
2nd one went fine until a chamfer attempted. it wobbled and blew it bigger than needed. fixed by using the screws to do the chamfer instead.
3rd was fine until program error made it do a second deeper pass but surprisingly didn’t wobble. (3rd attempt)
4th misalignment when flipping, my bad. fixed. (5th attempt)
5th as seen in the first post. (6th attempt)
6th i got distracted and let the spindle drop… it gave me an unplaned corner bevel. should be fixed by keeping the z active same as #5.
also have a problem with bed leveling apparently. my second decent one has the pattern fade on one side. (not in pics)
i have 2 left and ready for the pattern but after those fail i have to buy more wood… I’m hesitant on trying it again…
the wood is cheap though.
I have heat shrink tube for the XY pipes that support the carrage but im afraid it might make it too tight. so i havent tried that as a fix yet. but it does seem that the bearings dont have enough hold on the pipes.
