The motors that we use are a classic NEMA style stepper motor. Unfortunately, we do not have any type of datasheets available for the motors that we use in our machines.

With that statement you shot yourself in the knee.

How should a device work properly if I don't know what to install?

Based on their lack of concrete data, it would appear that Raise3D has a policy of minimizing the internal workings of their hardware - which is their perogative. Of course they know what the vendor part numbers are of the parts they install; you just aren't likely to obtain it from them unless they decide to release the data. They have no obligation to do so.

It didn't work with your motion controller board connector pinout request, or the stepper (there are several types depending on function) motor details. Are you starting to see a trend here?

Unless they decide otherwise, you have been given your answer.

What is your role in Raise 3d? Maybe you can put your energy into troubleshooting. E.g. the data transfer from the controller board to the motion board .... my Prusa i3 Mk3 is better. Print a cylinder with 50mm diameter in the vase mod on an E2. The printer is overwhelmed. 3500 € costs a printer that has nothing on it. Have a nice Weekend

With this setting, Raise 3d can only lose. I would be embarrassed if I didn't have any answers to questions about a device. I only hide when I screwed up :)

As a general rule, when it comes to expensive purchases, (whether it's an automobile or a high-end printer) I let the first adopters discover and report any bugs, opting to wait until I know a product review assures me it is reliable enough to justify the expense. I operate and maintain three Raise3D printers - none of which is an E2, for the reason just described. You gambled on an expensive, new model, and it appears you may have lost, though time will tell. I hope the company can sort things out for you, but in an earlier post you said the printer was going back. Why prolong your misery, or is it all just talk? By all means, enjoy your Prusa - they make a really nice printer. But if your printing experience is miserable and you can't get the support you feel you deserve, by all means, why not obtain a refund and move on with your life?

After making online threats to a company in a futile attempt to intimidate them into providing information, (your Duet posts) it's little wonder you are receiving zero cooperation. Are you really surprised you are not able to obtain a part or model number of a simple COTS component?

I contacted Raise3D last week for some technical information regarding the Pro2, and received a comprehensive reply within 24 hours. I am more than pleased with their technical support so far. I doubt mine is an isolated case. Online forums are a venue for a minority of people to complain, which gives the false impression that a product is faulty. The numbers of posts of people who sign up, ask a few questions and move on far outnumber the posts of people who are regular visitors. The vast majority of Raise3D owners are busy using their printers as intended. This doesn't mean your complaints aren't valid, but . . .

Maybe factory support is only available in the US and on this site, (Raise3D has an online and telephone call support center in Los Angeles.) It appears all technical support issues are referred to the originating reseller in the EU. Do the EU distributors have factory-trained technicians to offer assistance? If not, hopefully they will in the future.

If you aren't satisfied with your printer or the support you need, there are other companies ready to earn your business. Again, Raise3D is not obligated to give you any detailed information regarding their products, any more than BMW or Mercedes will tell you what's inside their vehicle modules or give you the operating code. Modifications are always performed at the owner's risk - for any product.

This is not the truth you want to hear, but it is the truth. (Raise3D can change any policy at their discretion.)

Enjoy your weekend too.

I didn't really want to say anything more about it, but the successful printers on the market are all open source. Users usually have better ideas than and improve the product on their own. The E2 is a good printer if you don't use the raise software and the controller board If you pull out the USB plug and connect it to a Raspberry with Octoprint, it does what it should. The quality of the prints is much better ... The transfer of the Gcode from the controller board to the motion board is a disaster ... .

All good points and I fully agree with the first two points.

During the Home Computer Wars of the early 1980's, I worked on the front lines at Texas Instruments in their consumer electronics computer division. Everything technical was kept from the public - especially the internal coding. I watched the price of the computer drop every quarter as the competition made their internal workings public and consumers created more innovative software that ultimately boosted their hardware sales as ours remained stagnant, even though we were told we were going to sell even more units as we continued to drop prices below the manufacturing cost. I found another job and told all my friends to do the same while they could. Most laughed it off.

Five months later, they pulled out of the home computer business and thousands of employees were laid off when the plant closed.

With the advent of online forums such as these, it is in any company's best interests to listen, determine if reported problems exist, and provide feedback. Raise3D is pretty good about this, but could do better. My purchase of an E2 is indefinitely on hold until the expected first year bugs are squashed.
