The SCM saga continues part 23/29
So weeks and months are passing and my cnc is still basically a large boat anchor.
Jeff- you've written that the drill head moves into position, does this mean the air cylinder has lowered the drill head down to working position? If so it sounds like the reed switch in the cylinder may not be made. If the head is indeed all the way down you may need to adjust the position of the reed switch. Be cautious when making adjustments like this. When a machine is in the automatic mode providing a missing input, in some cases, will allow the machine to progress in the program. An operator died at a factory I worked at due to those circumstances.
If the cylinder is not activated you'll need to determine if the controller is sending the output to the valve to activate the head dropping.
Seems to me you need to reload the operating software. The “fixed cycles” maybe not fully loaded.
We went through this when we had a problem with our operating software and it had to be reloaded as the fixed cycles did not fully “take” Boring block would come to the drilling point but not descend.
You never said what model you have. If you go into MDI can you drop any of the boring spindles? The way the Scm machines works is all the calibrations are based of the #1 boring spindle.
What are the length of the drills in relation to each other in the tool library ?
Go through the basics of calibration, sorting out lengths, diameter, symmetrical behavior
If it’s coming to the area to drill are you sure it’s not a fixed cycles issue ?
What does scmi state your error means ?
Jeff, our machine isn't even remotely the same as your SCM but we had a very similar situation happen. Our machine runs on a PC (WinCNC).
I'm sure it's not a 1:1 comparison of yours, but here is what we had happen.
Machine would do any cuts/holes in a nested sheet of cabinets up to the point that it needed to do 5mm drills. It would go pick up the 5mm bit and then abort the program with an error that said "soft limit Z".
If we ran sheets that had no 5mm drill, things cut without error.
After a few hours of head scratching, we figured out the problem was due to operator error by accidentally clicking "Calibrate Z" instead of "Calibrate Tool". He had just installed a new 5mm bit and was trying to calibrate the machine for the new bit.
On our machine, that mistake recalibrated the 5mm drill to think that the top of the spoilboard was basically the very top of the Z travel, since that's where the spindle was sitting when he hit the button and was holding tool 5.
It didn't effect any of the other tools.
You get the cnc going yet? Your first post was a couple months ago, that is unbelievable that SCM can’t get it working.
They have no idea that businesses need their equipment to STAY in business. They sit in their office collecting their hourly wage and have absolutely no concept of how the industry works. The field techs come to the shops with their briefcase full of hand tools and a multimeter and charge you north of $100 per hour to fix your machine. I just don’t get it. The shop they are working at has probably a few hundred thousand dollars of equipment, and some shops a lot more than that and they have a hourly rate less than the tech. Blows my mind.
There was another company selling Casadei machines (Another SCM company) and they had the same problem, no one has a clue how to fix them so a bunch of machines being used as dust collectors.
Anyways just my two cents worth. I feel for you.
Unfortunately nothing has changed, apparently no one knows how to fix it.
I will never buy anything SCM ever again.
