Pressure / linear advance?

Hi,

I'm printing some small pieces with lots of corners atm that need to fit together and I'm noticing a pronounced bulging in the corners.

On myself build printer with a duet I had combatted this issue successfully by enabling the k-factor /pressure advance.

On first search I couldn't find details about it in the documentation, can someone point me in the direction on how to set this up for raise printers?

Cheers
F.

That would also be of great interest to me, as I am facing the same problem!

Which printer do you have? Pro, or E? The only printer we have that pressure advance counld be tuned for should only be the E2.

@ Vicky, that could be realized with a (long overdue) firmware update for the Pro2. Why don't you do that?

@vicky@raise

I use the pro 2. Would be great indeed to unlock this for all printers. Seems like most controllers/manufacturers have implemented some version of this.

Pro2 has custom and closed source firmware that doesn't include linear or pressure advance

That means that we bought this expensive printer as an isolated solution and that NO firmware updates are to be expected which include new and useful functions?

The fact that its closed does not explain why you shouldn't try hard implementing new features.
BTW (off-topic): You company's reaction to all the hightemp longterm-print issues is soooo poor! You just ignore your design failures in a way i never saw in any other company. Vicky, i ask you: WHY?? Do you really want to watch running away customers? It is such an effort getting your printer work properly for every customer who wants more features than every 300 $ printer can do even better! And the really sad aspect on it is the fact that it wouldn't be a great effort for your company doing an firmware/hardware upgrade/redesign in order to get a really good product.
once again: not answering or pro forma answers says a lot about your strategy, and every potential customer can read about it here in future!

Well thats to bad, but i hope that doesnt mean i wont be implemented at some point?

It should also be possible to implement this on the slicer level...

The firmware of the Pro2 is up to date from 2018. Marlin is now much further and many innovations are withheld from us. Except for a handful of users, nobody seems to mind what horrifies me personally!

We actually did try to apply it in Pro2 series a while ago.
But in the end we found that adding this feature would cause other motion control issues and haven't found another solution so far.

Are there any problems implementing it on the existing hardware? As I have read, the new E2 has already included this function.

The motion board and firwamre on E2 are totally different from Pro2 series printers.
E2 is running a version of Reprap firmware which allows you adding Pressure advance.

@Vicky,
the Pro2 has been produced and sold as we know it since 2018. The Pro2 costs more than the E2 and is intended to appeal to professional users, i.e. buyers. Now the motion board is out of date, the system is closed and every owner and prospective buyer wants a system that can be kept up to date. I am a technician and I am sure that a hardware upgrade would be feasible and affordable. Have you already considered this option? If customer satisfaction and loyalty are important to you, then you should think about this option very carefully. I would appreciate it because Raise should have noticed that we are actively improving the printer and its quality! It would be time to prove to us that you honor our commitment and offer a solution to keep the firmware up to date.

I am 100% the same meaning as Markus64.

I will forward the requests over to developing team to review.

Just wanted to state that I would very much like this as well and would never consider anouther.raise product otherwise.

Hi, would the dev team implement this feature?

Unfortunately, with the current configuration with the firmware, adding pressure/linear advance won't be an easy process. We will see how we can make it happen in future versions.

The raise3D Pro was on my wish list. But it looks like this is an old model that cannot keep up with future functionality.
