Problems with PRE-echo on models

[rpollack]

Denis - please post here the best print of that model that you made with your M2 kit. The prints you posted at the beginning of this thread are low quality. I would like to see that you are getting the same print quality as the other people posting here. We have printed this model and the print quality is fine.

We do not sell kits on Amazon.

Its funny you are the only one having these problems out of all the other m2 owners. The problem is not your nozzle. The makergear nozzle and extruder is a great design and it gives the exact same results as the e3dv6 i am running. Fact is, everyone here on the forum tried to help you but you ignored all the advise and did nothing but make demands to the people trying to help you. I really do hope you send the printer back

if this was a "feature" of the printer you can tell me 3 month ago I'm just change the extruder

All problems are best solved by patience and careful debugging, not by complaints and flame wars.

I've had plenty of minor problems that took me a long time to figure out. Your ripple problem is, in my opinion, a very minor problem of the sort that 3D printers have all the time, and for many reasons. I would have to see that you have done a complete and unbiased study of the problem before I could conclude that you have fixed the problem simply by swapping extruders, as opposed to the many other things you have done to the printer. There is no way that anyone could reasonably suggest to you that the solution would be to swap out your extruder.

It's difficult to conceive of what you are trying to do that requires so much accuracy that you can't tolerate a small ripple echo, which could be sanded down, anyway. If you need that kind of accuracy in fine detail you should be using a resin printer like the FormLabs Form-1, not a filament printer.

You should consider the positive side, which is that the M2 was able to print such a small part, something that many other printers would suffer a low yield trying to print; the M2 was built in an open hardware and software framework that ALLOWED you to replace your extruder, motors, electronics, and firmware with 3rd party equivalents, again something that many other 3D printers would now allow you to do at all.

Denys, where are you located? I'm considering buying your machine from you so you can get something else, want to see how bad shipping will be.

Denis - please post a photo your best print of this object on your M2. The photos you posted at the beginning of this thread show very poor print quality. I would like to see that you are able to at least get the same print quality as the other posts here. Did you mention anywhere that this was a kit and that you are in Ukraine (which adds to the support challenge).

I can get the same quality as photo that I put on amazon. When my father fix your nozzle I will print the perfect model on your perfect M2 printer.

are in Ukraine

And....? What is the problem with this? I don't ask you to speak with me in Ukrainian. You never ask me to send the printer to you.
If I was 20 miles away how you suppose to fix the problem if you even now try to tell me that is great feature of the world and not the bug.
I know that make nozzle is difficult but it's not reason to blame me in your slow support. I spent 3 month on communication with your support and ask about problem on the forum with no solution. So you don't know about this problem and about solution. How you suppose to fix this even I will be 20 mail away?
Even if you get the printer at your office! How you expect to fix if you think that is the great feature. also your printers that you ship today to the costumers has the same problem and you can easy reproduce the problem 3 month ago and find the solution himself.

Denis is now also demanding a full refund (minus return shipping) for a kit that was shipped in June.

No. It's not true. I ask for refund more than 11 days ago (yes I know about your slow support) after many-many-many days of tying to fix the problem and heroic attempts. Now when I know the reason of the problem I don't ask for refund.


Hay guys I found the serous bug in your printer and you make me guilty in this? I think you should say "Thank you very much." since I spent lot of time instead you.

[DenysNazarenko]

We do not sell kits on Amazon.

Yes. I know. But your printers on amazon have the same nozzle.

3 month you try to tell me that problem with printer related to my and my father engineering skills. No. We assemble your printer correctly. Also we find the serious bug in your nozzle. So the printer that we have the same that you sell at amazon. Yes? Or you ship to customers on amazon other nozzle?

[DenysNazarenko]

Its funny you are the only one having these problems out of all the other m2 owners. The problem is not your nozzle. The makergear nozzle and extruder is a great design and it gives the exact same results as the e3dv6 i am running. Fact is, everyone here on the forum tried to help you but you ignored all the advise and did nothing but make demands to the people trying to help you. I really do hope you send the printer back

I'm already publish the photo of the print that made with cheap Chines printer. Ok now you know about other printer(e3dv6 ) that also has problem with the nozzle.

btw. Now you know how to fix pre-echo problem

Offer still stands to buy your printer.

All problems are best solved by patience and careful debugging, not by complaints and flame wars.

Yes. I spent 3 month to solve the problem step by step. We try to replace motherboard with arduino mega. we try to replace electric motors.
We give this printer to 2 different places to give a chance for other people to solve the problem. we spent lot of time and money.

Now when we find the solution I get response -
That I'm idiot from Ukraine that not pray on the "great" nozzles from MakeGear.
So flame about how community and MakeGear company accept that I found out and my solution.

Also flame about how MakeGear company will solve the problem. Seems the customers will get broken nozzles on the Christmas and detail explanation about "mechanical vibration".

I've had plenty of minor problems that took me a long time to figure out. Your ripple problem is, in my opinion, a very minor problem of the sort that 3D printers have all the time, and for many reasons.

This is the photo of the model that print with cheap Chines printer. this model don't has this problem.

Once again. I spent 3 month and long time before. Only communication with support takes 3 month. Any other will ask for refund immediately.

Actually I get this problem with large details too. We create small model to reduce waste of plastic. All time the problems with embossed text or hols.

It's not true. Other customers also have the problem. This is the prof-

The true is that M2 has the problems with nozzles and you don't want to accept this Maybe because you are satisfied with low quality printing with humps.
But it's your chose and taste. I prefer the high quality prints like this that made with cheap Chines printer that cost much cheaper than M2 -
