Comparing motion controllers...

[JAZZCNC]

What do you say about the IP-M lacking electronic backlash compensation?

I say for router it's not required. If you have that much backlash that it shows in wood or light aluminium work then you need to address the problem. Software won't help you.!

To answer George(Komatias) mentioning the Big boys using backlash comp then it's like comparing apples with oranges. There control software is in another league to anything we use and can't be compared. They are also talking about tiny tiny amounts of backlash that you could only dream about getting close to achieveing.

The ESS is perfectly good Controller I never said it wasn't and I do use them. But it offers very little other than individual homing for a stepper system. The Extra frequency it allows you can't use. The BOB is potential problem despite what may be said and unless you buy decent quality BOB then it's like a lottery to how long it lasts or starts giving you troubles. In the past I've built machines with BOB's which work fine for years then all of sudden for no apparent reasons hair pulling issues start creaping into the machine. 99% of the time BOB is the cause.!

Regards using Timing belts then you won't loose any precision and keeps perfect sync of screws. If the machine isn't too large then I'd use Belts over Twin motors every time.

Well i could "close" one of the short sides of the machine and put a belt design there. I would also save some money using 3 drivers/motors instead of 4. Could put those in som decent high voltage leadshine drivers instead.
The squaring problem would be gone and based upon what you told me the IP-M feels like a pretty bulletproof controller... It feels like the right thing to do. Its easier to make the machine better if i would like to once Ove got it up and running.
Should i make a belt tensioner or do i build it "right" directly?
Btw the machine is roughly about 900x700 mm...

How can Boyan or anyone comment when they've never used the IP-M or had any dealings with Cslabs. ?
The Pokeys is ok and for the money gives good value but it's not in the same league as the IP-M or Cslabs products. Also it does require a BOB because it's I/O are not protected. The I/O logic is still 5v and comes with all the potential noise issues low voltage can give. There's much more to Cslabs than just being in case.!

Cslabs are very good as a Company and at software, they always respond to any questions or problems. not always instantly but in general they come back to you quick enough. Which is more than lots of hardware manufacturers do. They do and have listened to requests for features that's exactly why the IP-M now does slaving, it didn't at when first released. So it's not fair for him to say such comments and condem the company just on some else comment.

I have no loyality to any manufacturer and trust me if the Pokeys was better than the IP-M or Cslabs products I'd be using it and telling you and everyone else to use it. That doesn't mean the pokeys isn't a good controller it's ok but it's not and I repeat it's NOT in the same league as the IP-M.

I spend a lot of time and money testing products I fit on machines and won't ever comment if I haven't used or tested them properly. But end of the day everyone as to make there own decison and work to different budgets. I just pass on my experience, if folks care not to listen then that's there choice.! . . . Personaly when someone with experience advises me I tend to listen.

The CSMIO is ~3 times more expensive than Pokeys, so really what we are talking about here? I have USA made non protected 5v breakout board coupled with Gecko that did not miss a step ever working sometimes 24/7 at 70 degrees C, by the way LPT, so at the end it matters if it works or not.

Personally I was talking about you Bad mouthing a Company and there product you have never used or dealt with. IMO that's wrong.

The rest is personal choice or budget driven. Pokeys is fine piece of kit which as you know I do use but it's not in the same league as Cslabs and if you'd used one you'd understand what I mean.!

I was at the point of buying the 6 axis controller last summer. I have checked a couple of times the price then and at the end i decided to swallow the pill. So i see price 640 or something then. I push the button and place the order, whaaaat, +23% +shipping =~800 euro

So thats why didnt like them at once. I started with them on the bad leg. I would have bought their servo drivers also. But i hate hidden costs and cheap price tricks.

Not that i am not saying that i will not buy or recommend their product. If Pokeys dont work right i will have to buy the CSMIO. Now that i see that the IP-S is cheaper, or again its some trick.
