Hi there!
New machine came in today - setup all done.
I can move on the X and Z axis no problem , however when trying to move on the Y axis ( at any speed ) it won't move and makes noises.
Any ideas why and how to fix?
Thank you!

When you turn the machine on and it asks to home all axis, does it do that?

sorry, both x and z move fine. when i slowly step with the y it moves, as soon as i try and make a fast movement with the y is stops with a grinding or buzing sound... please help! :S

Since the Y ball screw is under the bed, take a look to see if the ball screw is moving when you hit the Y + or - on the controler

it does when i move it in slow increments but as soon as i try and move it in fast motions + or - it stops

The other thing to take a look at is if the entire gantry is able to move. Is something blocking it from moving towards you when you press the Y- key.

It almost sounds like the coupler that connects the stepper motor to the ball screw may not be tight. Which mean the stepper motor is turning, but the ball screw can't.

That is what I mean. Because of the weight of the gantry, trying to move it fast may be the problem!
When I got my machine, I checked all the coupler's on all axis and tightened them down with a allen werench. They were all loose. You have to consider this machine was shipped all the way from Taiwan. On a ship, on several trucks and then to your house. Things move and get loose. I also went into the case and made sure all the wire connections were tight. Even after that, the connection to the X stepper motor had come unplugged and I had to take the left side cover off the gantry and re connect the plug to the stepper motor.

The coupler for the Y axis is at the back of the machine where the connections are. You will have to go look under the machine bed to find the coupler and make sure the 2 set screws are tight. The allen screws are metric, so it would be a good idea to have a set on hand.

i may need to tighten things up. i hope its that simple. i turned down the speed to 1000 mmps and it worked fine but its way too slow. as soon as i turn it up it grinds again.

Jenna: 1000mmps is 39 inches per second. That 2450 ipm. That won't work at all. The machine can cut at 200 ipm and that is super fast. I hardly ever cut faster than 150 inches per min. Most of the time, it's about 60-120 ipm. That is why the machine is grinding. It simply can't run at that speed. Depending on what you're cutting even at 150 ipm it's never really cutting that fast. It has to slow down around curves. If you were cutting in a straight line, the machine could possibly cut at close to 200 ipm. ipm= ( inches per minute)

Jenna, just checking, mine is having the same issues, AR16, only about a month old. I am going to remove panels and climb under this afternoon. Was this your problem?

Jenna: After reading your second last post, your cutting to fast! 1000mm per second is 2,400 inches per minute. 200 inches per minute is as fast as the machine can cut. The rapid speed is rated at 320 inches per minute which is what the machine can move at while moving the X & Y to adjust to the work piece.

Checked my coupler and this is not the issue. When I move the Y axis in the positive direction it comes to a stop about 1/3 of the way up the bed. When I tell it to home, it will drive to home but the Y-axis hits the edge of the frame passing the home flag. The home flag is lighting well ahead of that so seems to be working but not telling the axis to stop. Everything in the electronics cabinet seems to be operating correctly. I think I will pull off the side gantry covers and make sure there is nothing obvious there but it really feels like a software issue where it thinks the Y-Axis is at its software limit. Everything seems to move freely and the servo is not even trying to move beyond that spot.

Which machine is this? I2R?
There are a few things that happen... when the ball screw bearing is put in the gantry it needs to be moved to the far end Y+ and then the little metric SHCS need to be tightened up. Otherwise there can be some binding. The other thing, since this is essentially a new install is to make sure the gantry isn't sitting on something and dragging. While I don't need to get under any of my machines super frequently, I need to do so often enough that I usually put the feet at maximum and then trim the machine up so it sits level.
I'm highly suspicious that some binding is occurring, either something to do with how the machine is installed, or perhaps the wiring harness.
