LaserPro GCC Mercury - strange

[jm_studio]

Hello
I have question for you.
I buy laser GCC LaserPro new Mercury.
If I cut or groove, I have problem with radius.

I sent photos of manufacturers and I got the answer......laser it´s OK.

And I have question .... he makes me laugh manufacturer ? or is it all right ??

Thanks

it looks like the shaft encoders on the motors are dusty or dirty , take the X and Y motor out , carefully take the black caps off and use a soft brush and brush the disc encoders off. Put motors back , make sure the belts are tight. Clean all the rails and bearings and lubricate them too, especially the heads rail , check the rollers dont havre caked up rubbish on them.

The "laser" looks like it is OK.

For everyone's information GCC Mercurys do not have external encoders, so the troubleshooting should be in this order :

1. Make sure that the X & Y motors mounts aren't loose / moving
2. Check that X and Y motors are OK and not "sloppy" when moving left & right. If they are then they have worn out and will need replacing.
2. Replace ALL rollers (and make sure that roller guides / linear rails are DRY and ARE NOT greased)
3. Check that belts are tensioned. GCC can provide the belt tensions if you have access to a belt tension meter - or contact a GCC dealer to see if they can do it for you.

My money would be on replacing the rollers should fix the problem, however Mercury machines are getting older now and to get 2-3 years hard work out of an X axis motor you are doing pretty good

Motors are expensive because they are high quality units.

Please let us know how you go!

From someone who has been factory trained by GCC in Taiwan and spent a couple of years maintaining everything from GCC Venus to the GCC GaiaII, I can assure you that you should never EVER lubricate the linear (X and Y) motion rails on a GCC laser.

When you do, they attract dust / dirt / grit which wears out the rollers too soon. It can make them wear unevenly, and even mask the physical signs of wear until it is too late.

The only exception should be the Z-Axis screws (up and down movement) which can be lubricated with the type of grease provided by GCC from new. I believe that it is Lithium-Moly grease.

Hello
Thank you for your answers.
I wanted to know your views.
I make model accessories and this is useless for me if the machine works like this.

My dealer called me, that tries to replace the motor X.

We'll see if that helps.

I am sad from it.

The GCC Mercury is actually a very good machine.

I would very much suggest getting it serviced before judging it so harshly.

I saw many people making models and parts with GCC Mercurys and they were all very good when *maintained* regularly and looked after

All the best with your hobby.

hi im sorry im not understanding your question ?
radius is not laser problem but software/file/draw/settings

You will find that this problem is not the software but something in the items I have already replied with.

The Radius issue happens when the motors, belts or rollers fail.

This I can guarantee.

sorry for me its still not clear ,what is the problem with the radius ?
is it the shape /the power settings in corner/speed in corner/or your suggestions.
on the picture i cant see what is wrong.
so i can understand the answer from chinese manufacturer,'laser is ok'

1. GCC Lasers are manufactured in Taiwan, not in China.
2. The radius issue is coming from "backlash" or "slop" in the x&y axis combines which makes arcs and radiuses become "flat" spotted.

Look closer at the image please

i increased the picture size and see it now

but it almost looks if the design of the letters are made in a square and the laserprogram
sees the end of the square as limit/edge and draws/cut straight line.
its always same part,to check,
im curious if he can put the material turned on the table and see if its still on the same place.

Hello

Sorry if I judging it so harshly.I hope that everything will be alright.

Machine is new(warranty) and I have to wait for a technician from my dealer.

Now I have tried the same graphics and setting on Rotary Attachment (paper tube) and it is better....so the problem will not be setting.
