Da Vinci Jr 1.0 Pro Firmware 1.0.2 problems (Page 2 of 2)

I think you should just return it if possible. XYZ is a Chinese company. I'm Chinese, so according to my understanding, Chinese company have not evolved to recognize the importance of customer service yet. Just like most Chinese restaurant, the cleanness of the bathroom always a problem. It is not that they can not do a good job, but deep in mind, they don't think it worth the effort. It is burned in our value system and not easy to change.

It take 10 years for most Chinese company to realize the importance of quality over quantity, some company start to appreciate the importance of advertisement and visual appearance of their product. very few company realize the importance of brand and pattern. Most company customer service is for decoration purpose. "Wait, customer service that speaks English? Let me check the salary range."

I think it may take another 10 year for Chinese company to really appreciate the importance of customer service and believe it worth the investment, before that, I doubt you will see major improvement. And if customer like you don't return their product, they will never learn.

As I said, XYZ printer use high quality parts and most part of the hardware is well designed. If you like the price and the enclosure as I did and are capable of doing the RAMPS conversion, I would recommend you buy from ebay for very low price and it will work with Cura and simplify 3D and 3rd party filament. otherwise, stay away from 3D printer build or sold by Chinese company, you will not get timely response from customer service. Currently, customer service that speak English are too expensive for them.

Most other Chinese 3D printer company use Cheap electronic parts and result in unreliable power supply and sd card reader, and there is no firmware update can fix that. If you do like CR-10, be prepared to replace the power supply and motherboard with higher quality one. And be prepared for longer waiting for customer service.

You don't know China, the 90% of them where all appears to made by the same company and same PCB design doesn't means the are actually made by the same company.

In China, many board and PCB are so called public design, they are not patterned, any small company or workshop can use the design for free and make them, and sell them. They are mostly soldered manually by hand with cheap electronic parts, terrible quality control, these company have not yet evolved from quantity to quality, and the life span of the product is unpredictable.

However, the product sale to United states are usually fully tested and will work for reasonable long time because U.S. law require free replacement but not in China. The sticker you see are usually the company that buy these public design boards form different workshop and test them and sale to united states. But if you buy them on ebay and they ship from China, the result depends. But they still offer free replacement most of the time because the production cost are extremely low. Anet A8, CR-10, PRUSA all use these kind of power supply.

Large company actually make the rest of the power supply, they have their own design and soldered by machine, you usually don't see solder beads on these boards and they have higher standard for the electronic parts they use. like Da vinci boards.

Do I need to tell them downgrade the firmware can fix the problem? It is not that difficult!

It is comments like this that makes one think you might work for or be associated with XYZ.

You say you are just a normal Chinese guy. If that is true then they could care less what you have to say to them and they will not listen to you.

But if they would listen to you then that means you have some sort of influence and you are not just some ordinary Chinese guy.

OK, sorry for bad English, that sentence supposed to be sarcasm, I'm surprised no one gets it. I still leaning how to get sarcasm right.

Call them and hound them. You'll get someone pretty quick. This is the last response I got last week.

We got the feedback of our Engineers in regards with this firmware issue.

We will be releasing a new firmware version by next week, I will let you know once its out.

Thank you for your patience.

I was finally able to update to 1.0.3 but my printer is still stopping during prints and saying filament jam when it's not actually jammed.  Yesterday it stopped about half way through a 9 hour print that's 105mm tall and said there was a filament jam.  I immediately removed the print and told it to load spool to see if it would feed the filament.  As I suspected, there was no filament jam because it fed just fine.

This seems to only be happening on long time prints.  I tried to print another object that was shorter but still had a long print time and the same thing happened.

try to feel the step motor on the extruder and see if it is over heating after long print. Da vinci Jr. use high current on motor drive and this is set digitally and can be further increased by firmware update. the optimal current for different motor can be different and that may explain why your phenotype is more obvious than others. You can also notice increased noise coming from the extruder step motor during printing after open the printer door/cover if that is the case. You will also notice warmer step motor after short printing and hot step motor after long printing.

Overheated step motor will soft the PLA and change its shape and the filament spin sensor will slip. However, after a short break, temperature will decrease, allowing the extruder to function. I don't think it is easy to adjust the motor current for Jr. you can either add cooling fan on step motor or get a different step motor that can handle higher motor current. I would recommend neither method if your Jr. Pro is still under warranty. Keep hunting customer service is the best option. (Is this right English expression? I'm not sure, saw someone use the hunting expression somewhere, correct me if I'm wrong.)

Did you press ok on control panel before shut the printer off? It might make difference.

There is clearly still a software issue, if you turn off printer when it is printing and turn it back on, you might found more problem even thought that supposed to be the intended improvement.
