I have had some serious issues with my new Leapfrog Creatr HS (Dual Extruder, of course) because of connection issues.
My Interface & Software
I prefer to use the PC to Printer method of operation since it allows for greater control than printing from USB (which has also not worked well for me).
I use the supplied software, Simplify 3D, which I am quiet happy with; easy to use and has (for my/ my needs) a great deal of functionality.
A Production / Design Engineer since the late 1980's working with Production CNC machines and programming (originally writing code my own code and performing trig calcs by hand). The last 10-15yrs working in Automotive (with Polymers; PP & ABS for vehicle interior/exteriors) & Aerospace Design
Using the supplied Leapfrog USB (1.8M cable) connecting my PC to the Creatr HS printer, I could never get this to work. I replaced this with a Belkin Premium 3M USB cable since my PC was not originally located next to my printer. However this work must better though I encountered this Firmware Unresponsive error showing up in the Communication tab in Simplify 3D software. The various steps to get the connection back involved shutting down the software and or the printer.
After logging a ticket on this I was informed that the cable must not be longer than the original 1.8M.
I was also told that I might need to use a Repeater USB type Cable. Checking on line for one with a Male USB (for the PC) and a Male USB-B (for the Printer) could not easily find one. I requested Leapfrog advise further on this but never received a response.
In the last 2 weeks since I received my printer i have attempted approximately making around 50-60 attempts to print with only 10 or so finishing the print cycle.
The ticket is still open regarding this issue. The last test I performed per Leapfrogs instruction and do not recommend you do this unless instrusted was as follows:
ON THE PRINTER
1. Remove the left panel from the printer.
2. Disconnect the USB cable from the printer motherboard.
3. Connect the original Leapfrog USB cable from my PC directly to the Printer motherboard
ON THE PC, SIMPLIFY 3D
4. Change the Baud rate to 250000
Then to report back to Leapfrog how the prints turn out.
Not only did the PC not connect to the Printer using the original cable but would strangely not connect using my new Belkin cable.
Once I replaced the side panel, I plugged my USB cable in the rear of the printer and since have not been able to make a connection between PC and Printer.
Leapfrog have advised Tue, 10 Feb 2015 that the problem is with the motherboard and needs replacing. A new board has been posted today.(I presume express) not a good start after 2 weeks.
Essentially I need to ensure that this printer can be successfully commissioned (to achieve quality / repeatability / reliability) as I intend to use this in conjunction with my business services as a Consultant Design Engineer (typically I work for large Automotive / Aerospace OEMs)/
Unfortunately this experience albeit brief so far has not given me much confidence that the printer is reliable enough to include it in my business services portfolio.
Hope this overview gives anyone with the same / similar issues some background detail that proves to be helpful.
I also look forward to hearing from others and their experience.
I do notice that there are others positing with less than positive results.
Yeah I have an HS too ... So on mine I learned that you cannot make the "USB PC to 3D Printer Connection" until after the HS has fully booted up, trying to connect prematurely to the machine won't work. Also if you are using the front or rear USB port and want to switch from one to the other, you just need to turn the machine off connect to the other port and then turn the machine on. You cannot occupy both ports at the same time. If you are using a USB Flash Disk in the front and want to switch to computer controlled mode on the back then you have to turn the machine off remove the USB Flash Disk then connect the USB cable for Computer Control via Simplify 3D and turn on the printer, after the HS is fully booted then you can initiate your software connection. My friend was using my machine and he really just rushed through the process and concluded the thing was broke, then I showed him the procedure and all is well. I haven't had the issues sending my jobs from the computer to the HS over the USB cable at all and I am using the stock USB cable, but I have noticed that there are a lot of rough edges on the procedure of using the machine where people get tripped up... Leapfrog support is helpful in these situations at least they are for me and I work for them.
I've been having the same problem of having stalled prints mid-way to a 10+ hours print. The Firmware Unresponsive problem in Simplify3D is really annoying and I have been having this problem since I have received a new motherboard; the original has gone kaput somehow, and the replacement is behaving funny :(
Anyway, just a little note to anyone else who happens to meet this firmware unresponsive problem through Simplify3D on really long prints, I suggest the following procedure to salvage the print:
The aim is to reconnect the printer and resume printing from the point where the printer started to become unresponsive. This could only be done if the printer could be re-homed without the x-carriage hitting the half-printed object during re-homing.
Are you still having the same error; Firmware Unresponsive?
Also I wonder which printer you have, I myself have a Creatr HS all be it, it is my second printer since the first one just basically would not work and after nearly 2 months of continuous emailing to the Tech Support folk they could not fix it and ultimately replaced it.
Fantastic you would think but if todays performance is anything to judge it by you would be wrong.
So I'm interested to hear the experiences of other users that might be using the same 'generation' printer as myself; happy to hear more about experiences - good or bad..
Really like to hear any other interesting / general observations also.
Thanks in advance and look forward to comments and thoughts.
I'm using Creatr Dual Extruder (not HS). So far I have recently installed a UPS and used a shorter USB cable. I plug both my printer and PC to the same UPS. This is based on an advice given in my ticket to the support team:
"Concerning the other question, an upgrade to a shielded shorted USB cable could be the solution. Also having the PC and the Printer on the same grounded outlet(to have common ground) can be very useful. Also make sure that there are no other big electronic machines on the same power group(like microwave / oven / water heater / Electrical Central heating etc.). Also PSU / other power cables should not run next to the Serial USB communication cable." -Pim R. | Leapfrog Research and Development
So far I haven't had that Firmware Unresponsive issue. But most of my prints currently lasts around 5 hours. I have yet to run 10+ hours prints. Only time will tell if these solutions fixed the issue.
I am just wondering how many others are in / have had this experience with connectivity as I.
I have received a replacement printer 2-3 months ago and have been patiently trialling and testing it only to still find that I get connectivity errors.
Earlier this year after receiving my first Creatr HS only for it to result in a mamoth 45-50 page long session between me and Leapfrog Technical Support to try and resolve this issue about connectivity never found a solution. The solution was to send me a new printer which I can now attest to sadly does not still work as it is intended.
Despite it have a USB port for standalone operation does not exclude the fact that there are issues occurring when running it in what I call normal operation, meaning from the PC via using a USB cable as I must have this to be able to calibrate and recheck the continually changing bed / nozzle gap.
Have any of you faced the same issues and what solutions have you found by the community or been offered by Leapfrog?
I would be grateful to here back to understand this problem as after 6months I am still not able to utilise the printer in a consistent manner with any real sense of reliability.
I am having the same issue, I think.
I also don´t get connected with the Creatr HS though I followed exactly the steps given in the IFU.
Background: I tried to print from USB stick which actually didn´t work out well: The extruder pulls the printed object from the bed and destroys it...I think the bed isn´t calibrated correctly and so I tried to connect the Creatr HS with the computer to calibrate the Creatr HS.
For now, I don´t have any clue how to fix this problem. I haven´t opened a ticket at the Leapfrog Service, yet, because I hope I might get some helpful hints here.
I would be grateful for any kind of help due to the fact that I can´t print as long as this problem isn´t solved....
Regarding the issues you are having with the calibration of the bed and the connection issue as well I would ask you if you have the latest software and firmware version for the HS printer:
Please make sure to install the updates in the order of the links:
- first the software;
- then the firmware.
