@tommegna The CoreXY system moves at 45 degrees when either motor is activated, to move in a straight line it uses both motors. So you are saying that horizontal lines aren't smooth, which is confusing as the motion is basically the same as when the machine is making vertical lines. That's why I think it's a bearing on the axis.

@Zax
I have a couple other Vendors I'm looking at buying from. I want to use T2laser for EleksEgg (Eggbot), EleksDraw etc.
Thanks,

Aha, answered my own question. That switch, when ON, provides 5v to the Nano from the Mana's onboard regulator, but it's normally off to allow power from the USB. So yes, you can power everything with the 12v power input.

Still looking into the serial stuff.

@josephjnk Yes, that's exactly what I said. The supported G-codes are listed in the Grbl github documentation, it uses a subset of the NIST G-code commands..

@WAFI I'm not really sure what problem you are having but Inkscape can save DXF files, these can be loaded into T2Laser to run an EleksDraw. It supports multiple pen colors, single line tracing and an optimizer, all of these features really help with the drawing machines.

@mrbazza Hi ! I was wondering how you can change the servo values. In addition, is it possible to vary the pressure at different paths in the same drawing ? Nice setup Thanks

@orialairo I only know how to do it in T2Laser. There's a configure EleksMana menu and you click the EleksDraw option.

I would just get one at the local hobby store but of course that's not so easy these days, depending where you are located.

This is usually caused by backlash (a symptom of loose belts), circles are a good way to check for backlash as typically the ends will not connect if you have this issue. T2Laser includes an option to disable bi-directonal mode which is another good way to check if backlash is the problem, as when the laser always scans left to right it will effectively mask the issue.

I did not have any spare pieces but I don't identify this as part of the machine either.

I wrote T2Laser software that supports Grbl 1.1 and has support, you will get much better performance from your machine.

@Bradbrad T2Laser will run using a virtual machine (bootcamp, parallels etc).

@Kevin-Harte As I posted in your other thread, wrong firmware. So I'm guess you have an EleksDraw and uploaded Grbl 1.1 which isn't compatible with these CoreXY systems. In the custom firmware load the Eleks Mana and then configure it with the menu to EleksDraw and everything will work correctly.

Elekscam has many reported issues, I suggest you use other software. T2Laser is a fully featured program I wrote as a replacement for the Chinese software, and using my default firmware you will get much better results.

Ah ok. No, even disconnected from the Mana board, the power supply box light is not coming on. Could be the power supply, or a faulty Australian adaptor. Narrows things down, thanks very much for your help. If I get it working, I'll buy a T2Laser license for the benefit of this support alone.
