I recently purchased a Bambu Lab X1C printer and quickly followed up with a purchase of the einstar Rockit scanner. My laptop is a little older and can’t handle the Rockit. Can anyone direct me to a laptop that can do the job (without breaking the bank). I know the specifications recommended, I just hope that someone can suggest a PC that has proven to be very good. Thanks!
I just purchased a rockit as well. My machine couldn’t handle it as well. So I recently purchased a Lenovo Legion pro 7i. It has the intel ultra 9 with 64Gb ram and an nvidia 5080 with 16Gb of video ram. Seems to handle everything pretty well. However I’m still not super satisfied with rockit. Def need the rewind function. I also have the Vega so it’s hard to change from that work flow.
Thanks for your helpful insight. This is my first 3D scanner, I’m new to the community. I spent hours and hours researching feedback and you tube videos before selecting Rockit. It seemed to be reasonably user friendly and could perform scans without markers on black or shiny objects (I’m wanting to do automotive related scans). I really appreciate your laptop suggestion, I will start looking for the Lenovo unit now.
Thanks again!
@droyalty Currently i am using the rockit on a desktop machine (AMD 9850X3d, NVidia 5800 RTX, 96GB DDR5 6000 RAM) and I have found 96GB of RAM to be insufficient on some occasions. Mind you I scan mostly smaller parts but use 7 line laser scan for high precision quite often. It is in that scan mode that I usually have RAM issues (probably due to the high number of points scanned).
I have scanned larger parts in crossline mode without issues. RAM requirements seem to depend heavily on your usecase.
I have also a Macbook Pro with 64GB RAM but there is no macOS version of ExStarhub yet to test.
With 3d scanning there is no such thing as too much RAM, only sufficient or too little..
@frydrce I agree. The software needs polishing. I don’t get why there is not ONE branch of software that gets scanners added as they are released and moves features forward. Seems much more dev effort to develop multiple sw in parallel for products with same functionality goals.
Are you finding being wired to your machine is producing better results? I haven’t tried that yet. I have only attempted a few scan with this since acquiring the Lenovo. Having the laptop plugged in seemed to improve the scan but I guess that is to be expected.
Also like you stated if I drop the resolution to say 2mm it seems more capable.
I’ve tried a large object (car frame) and also a detailed object (cylinder head). The frame I couldn’t complete and the head turned out of but missing a lot of data.
I have seen no difference in quality or stability in wifi mode compared to tethered use.
Having the Laptop plugged in will give you an improvement in nearly all instances with NVIDIA cards, laptop manufacturers tend to limit power draw of the GPU by limiting GPU frequency when on battery.
Some gaming laptops with higher end cards even switch to cpu integrated graphics when not plugged in.
I have not had the opportunity to scan car frames as of yet because my workstation is in the office and my only laptop currently available is a mac. Eagerly waiting for that promised mac version to be mobile with the rockit.
I have scanned several metal parts up to about 30cmx30cm with varying success with global markers on a rotating scanning table. Generally I have no need to drop resolution in crossline mode, its the parallel line mode scans that sometimes hit the memory limit.
Trick with the metal parts is for me to either use scanning spray (shiny metal), if it is dull metal I can usually do without but one has to get the brightness adjustment right. I feel that the preview scan does not really aid in adjusting the brightness correctly - you need to get a feel for it.
Coded markers support would really help scanning large objects in multiple passes as every coded marker is not just a dot but also references orientation in space and can benefit stitching multiple scans greatly - but is unfortunately not available with exstar hub.
Why do you think your cylinder head scan had issues? Reflections? Are you using markers?
I’m not 100%. I am not using markers. I really want to be able to test this as much as possible without them.
The Vega is highly capable but it requires markers so I am really trying to use laser scanning only without markers for now.
I will post my cylinder head scan shortly but yeah I think reflections were mostly the issue.
also sorry op for high jacking your thread. But I think our discussion here will help you later.
Why not use global markers? I have no experience with the Vega but with the rockit they aid tracking in laser mode tremendously and you do not have the hassle of putting dots on the object and removing them later. Global markers really upped the speed and quality for me.
I am using on object markers very infrequently and only if absolutely needed.
My first attempts with global markers was just putting 6mm markers randomly on a black rubber mat, doing a global marker scan and then put the object on to scan. Night and day difference!!
Made several scans with the mat and because of the massive improvements I 3D printed a rotating 335mm diameter scanning table with 6mm and a few 3mm markers.
It is a one time effort to make a scanmat/scantable - the expensive commercial offerings do not do anything differently.
For objects I 3d printed 3D scan tools - dodecahedron marker holder by Trinom | Download free STL model | Printables.com for the rare cases where i have to scan big objects like door panels or hoods but I have not used them in a project yet.
Because of the imaculate tracking of the global markers on the scantable i can reliably do slow parallel line detail scans by just rotating the table by hand. Tracking is absolutely reliable as long as the object to be scanned does not cover too many marker dots on the table. Does not disprove the method. Just be aware that the scan mat/scan table needs to be large enough for the object and still keeps enough markers for tracking visible.
In my case on the 335mm diameter table a 300mm circular object was the largest i could still scan with global markers method.
Yeah I’ve been trying big things mostly. Car frame a few motorcycles.
I have used reference with ir scanning but I was hopeful the lasers wouldn’t need it but maybe that will help and I can increase the resolution.
Hello folks, I hope to get into the finer details like you all are discussing. Maybe I can start the learning process, just came home with my new Lenovo Legion Pro OLED with NVIDIA RTX W/16GB, Intel Core Ultra 9, 64 GB RAM, etc. Wish me luck.
Make sure to download the drivers for the graphics card. Gpt can help you set up the optimization. But there is a drastic improvement making a few slight tweaks.
Congrats! Have fun with your new machine!
Well, new Lenovo Legion Pro in hand, software installed, einstar Rockit attached - success (I think). Rockit calibration tested my patience, though I sometimes browse too rapidly through instructions (who needs them). My first scan (black computer mouse on black surface) didn’t turn out well - though I could see some of the mouse shape. I didn’t try any adjustments and didn’t use markers, just wanted to see if the scanner did anything. Bottom line, I’m happy with einstar Rockit and I greatly appreciate the advice on the Lenovo laptop. Dave
Glad it worked out for you!
I went through some motions today and will say I did try to scan a very featureless item. It’s a hood from a 1971 Porsche 911.
I used the rockit, tethered and untethered. I used the Vega and I even went old school and broke out the original einstar.
I tried all units without makers. The Vega excelled over the other units.
I went back and added markers to be fair since the hood was fairly flat. I then proceeded to use all scanners again. I tried to use similar setting on all and use medium resolution.
The Vega excelled again over the other units. I tried the rockit in ir mode and had zero luck. I put it in laser mode an it was at least functional but lost tracking over and over to the point I was ready to quit. But it was a usable scan.
I tried it again tethered and it seemed worse but maybe that was due to being restricted to the laptop.
The original einstar seemed to not lose tracking however the data didn’t seem useable. I would expect for a hood that was flat and white.
I did have higher expectations for the rockit since it is the new flagship.
I guess we wait for the next update.
