Works in progress / Re: 1st 'Beta' release of the MachSteelBlue Screenset

« on: June 18, 2007, 01:14:07 PM »

Hi santiniuk

Couldn't resist having a look with the screen designer and I've re-assigned the offending OEM codes to the buttons and switched the LEDs around and all seems to be OK now. I've taken the liberty of attaching the screen but I appreciate your comment re your time. I'll continue to use the version I've amended and see how it goes.

Screen 2:
switched mac coords from 240 to 256
switched De-ref all axis from 178 to 240
switched offline from 256 to 178
moved yellow led above offline
moved red led above mac coords

regards

Stirling

you've got me intrigued now regards your power supply. I looked up your motors and arn't they 2 and 2.5 Volts? if so that would mean that you're way over the max 20 times rated voltage recommended by Gecko or have I got your motors wrong?

I cut wood exclusively - mainly electric guitars but trying to get a small business running, offering anything I can handle on the machine.

Hi olf20

I'm sure there are folks here that know a lot more than me but as it's quiet I'll pitch in. There are basically two things to consider when it comes to the gearing. One is resolution and the other is mechanical advantage.

with 1:1, your 3inch lead, 200 step/rev motors and the G201's 10 microstep capability, the max resolution you'll get is 3/2000 or 1 and a half thou. More than fine enough for wood! and up to you for metal. However bear in mind that this is theoretical. The quality of your mechanics with regard to screw pitch accuaracy and backlash etc. will diminish this from the theoretical. Also the microsteps are not guaranteed to be exactly a tenth of a step, all that is for sure is that every ten microsteps will equate to 1 full step. so your true accuracy will be again somewhat less than the theoretical.

with ref to mechanical advantage I don't know the weight and drag of your Z axis but I'd have thought your motors should be more than OK at 1:1 as long as your power supply is giving them plenty of VA to work with. I'm running 260oz/in models at a lead of 20mm on XY and 5mm on Z and nothing will stop them - they snap G-clamps like toffee.

Hi artiom

Mon Français n'est probablement pas aussi bon que votre Anglais. Les moteurs ont-ils jamais fonctionné ? Est-il seulement avec Mach3 qu'ils ne fonctionnent pas ? Pouvez-vous "jog" les moteurs dans Mach3 ?

Si vous employez le contrôle métrique le "feed rate" dans le "roadrunner" pendant qu'il est placé à 60 et il n'y a aucun G21. 60 mm/minute sont très lents.

En outre, utilisation red-red/white et green-green/white. Votre méthode emploie seulement la moitié de chaque phase. (Pratiquant mon français - je vais là en vacances le mois prochain)

Hi Chip

Thanks. I'm floating them at 5v and pulling them to ground when triggered. Your suggestion about the debounce seems to have done the trick so I'll keep an eye and see how they go.

Re: Willem's comments, does anyone have any views on the best version of Mach3 to be using on a "live" system. Thanks Willem by the way.

Hi Willem

Isn't 2.00.076 a development rather than lockdown version? - yes Chip's solution has done the trick. I'm a wood n plastic cutter so no problems with the switches I hope.

Willem - Thanks, is Mach3 R2.00.065 the latest? I think I misread the downloads bit and just went foir the first I saw that was a lockdown i.e. 1.84.

afn09556 - thanks - set it to 2000, then 1000, then 500 and all seems fine now. I'm guessing these are millisecs and I should choose the lowest that works right?

Hi afn09556 - thanks will give it a try today.

Willem - not sure why your message isn't appearing here (got the email notification).

I don't have a g73 backoff under ports&pins/mill options. I'm using VR1.84 - is this the latest version?

Hi santiniuk - thanks for your reply

This doesn't happen on the standard Mach3 screenset - just SteelBlue.

Thing is - on the MDI,  LEDs are on different buttons and buttons are in different order so I'm wondering if something got switched.

Cheers
