![]() ![]() Removing anything else seems like a major disassembly project.ġ. I have removed the accordion-style guard along the bottom of the arm, the plastic curtain cover on the front, and a small access hatch on the top of the arm to see what I could see. On the IS400, it looks like the y-axis lead screw is motor driven. I am still hunting around, trying to locate the source of the issue. Yes, the text is supposed to be US BLOCK 1L from the Gravostyle library but starts looking like scrawled handwriting by the end. Last edited by Kev Williams 07-07-2015 at 10:58 PM. Good luck- I do believe your problem to be mechanical, just have to locate the source! That's always fun on someone elses parts. Electric issues are usually much simpler in behavior, like normal engraving ceasing and the machine proceeds to engrave a straight line towards infinity. ![]() I've never seen an electrical issue do this. and I've seen stranger things! The nice thing is, if it IS mechanical, then it's likely an easy fix, nothing more than tightening or replacing a few fasteners. Maybe the entire rail assembly is loose, it would explain all of what I see in your pic. OR, is the slippage occuring on the left side as the machine returns to the left to run the next line- Since the machine zero's itself before it starts any new engraving, that might make sense. Or none of the above? The issue in my head with a loose set screw or belt is that the text should run UPhill due to slippage, but yours is picking up distance on the right, not losing it like it should do if a set screw or belt was loose. My thoughts are you might have a loose stepper motor pulley set screw(s), or if the lead screws are belt driven (I don't know if the 400 is belt driven, but I do know the screws on my IS7000 are belt driven), one of the belts may be extremely loose and is skipping. I haven't had to dig into mine since I've owned it, but knowing it's design, with the head moving and resembling a fist on the end of your arm, leverage effect caused by the weight of the cutter head comes into play. Something tells me it's supposed to look like normal block! The line spacing increases slightly from line to line, EXCEPT that it decreases from line 3 to line 4, then increases again.įinally, I don't know if the text is a basic block, or if it's supposed to look like handwriting. not only does the text start running downhill, each new line of text runs more downhill than the line before it. I messed with your pic so I could see it a bit better, then drew the lines on it, starting at the baseline of the first numbers on the left. My money sez that there problem is purely mechanical. Wow- that's not 'math' issue the computer is overcompensating for, and I doubt it's a controller issue. ![]() If you're still getting runout, then you may be looking at a controller issue, or bad data (try changing the USB cable) Run the job- if everything lines up correctly, then you know that's the problem. This will slightly change every other dimension within the job, and you'll never notice the difference to look at it. The fix? Change the height of the text or graphic you're engraving, by. My BIL fights this issue with the old C2000 he runs. It always happens when I hit that magic number. 21" or so), and run a matrix of this across, every next STOP will be about. On matrixed jobs with identical text, the movement just keeps adding up.Įxample, if I engrave the word STOP on my XT machine at a certain letter height (I forget exactly. When this happens, the work is now out of position, and so is everything that follows it. Meaning, the stepper motor moves to the next highest possible dimension. HOWEVER- there comes a time when a stepper motor is told to go to a certain destination point, and the metric equivalent of the dimension is split. It's a fairly simple conversion process for a computer to do. We in the USA have to deal with SAE dimensions. ![]() Virtually every stepper motor on the planet (that I deal with anyway) has its movements based on METRIC dimensions. My opinion of WHY may sound like I'm out in right field, but it's the only thing that makes sense to me. I've run into this problem at various times with all my CNC machines. ![]()
