Hi Phil apologies for slow response, life keeps getting in the way. Is the sheet on the model pagoda the same pitch as i am using previously previously - approx 2mm between corrugations and 1mm high? Looks a bit bigger from the picture but difficult to be sure? You have now got me wondering if i have been using too small a pitch? A WIP Picture of my latest project hopefully shows what i mean, the yellow card on the roof is a lot coarser pitch (approx 3mm, vs the walls ~2mm) any further advice welcomed, so i can acquire the right stuff....

Hi Paul thanks for the leads, appreciate the time taken to respond. I think the top one is a little coarse, counting the corrugations has driven me mad! bottom link looks like the right sort of stuff, will try and contact them in the morning as probably outside office hours now. thanks again and regards Paul

Good morning all please can i pick you collective brains. I have used Micro Flute single sided corrugated card to represent corrugated iron on 7mm buildings, My stock is running out and I can't trace any similar on the net... The product is I think F Flute, approx 2mm between corrugations and 1mm high. Can find plenty of E Flute but this looks too coarse to my mind.... Any leads would be apprecaited thanks in advance Paul

Taking an engineering student to the Tate Modern on her 21st birthday after a bottomless Presseco lunch is probably a similar experience, we weren’t left wondering about her opinions on modern art.

Hi Paul. Items safely received and fitted, sounds great, far better with the sugar cube speak under the pcb than the 20mm speaker. Thanks again for the advice, gave me the confidence to proceed Kind regards Paul

Hi Paul good to talk this morning and thanks for the very clear and understandable advice. Look forward to receiving the new speaker and keep alive in due course. Probably have been easier to buy the full DCC/Sound installation kit from you to start with, certainly less confusing, but I learn best by making mistakes! kind regards Paul

Hi Paul thank you for such a prompt and helpful response, guess that its only when some points out the obvious that it all falls into place, why am I struggling with the 20mm speaker when I easily (?!) put a smaller one in the body. Could you be so kind as to recommend a suitable speaker - I have checked your website and can't seem to see a list of speakers - not sure if you sell them separately? I guess you locate them in the void under the pcb/socket in the firebox? As a follow up, the speaker I fitted is a 4ohm, if my reading of a few websites is correct, I should get more volume from an 8ohm speaker - at similar amplifier settings and size?. kind regards and thanks again Paul

Hi my entry into todays "most dull question" competion is below. I have recently bought a Minerva Peckett, beautiful loco, superb service (ordered Sunday and delivered Tuesday), along with a Zimo Mx645R sound decoder and 50331 Loksound 20mm speaker from Digitrains, again ordered Sunday and delivered Tuesday. Have successfully fitted the chip and run the loco run up and down on my 1 yard long test track, I have also successfully fitted the speaker directly to wires off the chip whilst the body is off, but wonder how you can embed the speaker in the recess in the chassis as suggested in the Minerva instructions, do you thread the chip wires down to the recess, if so how, they aren't long enough (I think) , or can you solder the speaker to two short wires and onto the circuit board in the recess, if so which of the four pads? Apologies if this is a numpty question, this is the first loco I have tried to fit sound to, and can't seem to find the information on the forum. Absolutely no criticism of either of the manufacturers and traders here, this is purely due to my own lack of understanding, in fact quite the opposite, great service received from both, Any advice gratefully received, and thanks in advance Paul

Giles I won’t argue with a master of the emblaser such as you, but having seen Monkeysarefuns superb gates and windows, he may not be as agreeable.....? I must admit that maybe I have let the side down and bought some of the problems on myself. As a test yesterday, I cut out SWMBOs name to try and prove the emblaser wasn’t a complete waste of money, so her comment wasn’t totally out of left field. Have had a totally frustrating evening trying to focus tonight, lens kept falling out before the focus was in place. Have left a question on the darkly labs community to seek some further assistance from Domenic. On a positive note, no gremlins got at the machine last night, so still cutting full patterns I will crack this, I will crack this, I will....... Regards Paul

And for tonights episode of Paul vs the Beast:- Firstly thanks for all the offers of help and suggestions so far, really appreciate the support. I have take the FFC out of both the laser head and the circuit board, no charring or any visible damage, gently wiped the contacts, refitted and retested. Woohoo!!! The machine now runs complete patterns drawn directly in cut2dlaser, imported from a dxf and a pdf drawn in inkscape. Repeated many times on many different patterns including lettering and no failures to date, so the incomplete cutting appears to be down to a poorly fitted FFC. Also the laser pattern appears to be different when cutting, somehow brighter (difficult to tell with the yellow specs thought). This is backed up by the cutting performance. Haven't changed focus since yesterday, and I don't think its spot on, but now cutting copy paper @ 70% 15mm/sec in one pass with a very clean cut. As an aside, SWMBO is now asking "can it cut out Christmas Decorations" (sorry - a mention of Christmas in April, I will go to the back of the class ) Need to pluck up the courage to have another crack at the mdf, maybe after a little focus tweaking. Seems like tomorrows challenge. to be continued............... kind regards Paul

Hi Giles thanks for taking the time to comment, and its ALWAYS possible that when I build something that is upside down, inside out or back to front. However, I did check on the Darklylabs forum when I refitted so don't think its the case here. Will double check again tomorrow just to be sure. Hi Jim thanks - created a simple circle directly in Cut2d and then looked at the .nc file, (now I know how, thanks). it has about 6 header rows and then about 10 lines of code, so looks very different to the original file I pm'ed you earlier. Ran a quick test, still an incomplete circle, but with a smaller gap. Tried then carefully holding the FFC at different angles and certainly seemed to make a difference to the gap. Some more scientific tests tomorrow, and possibly refit the FFC, and then maybe an email to Domenic if that doesn't cure the problem, I have emailed him previously during construction and received a very prompt, courteous and helpful response. onward and upward! kind regards Paul

Jim thanks for such a prompt response. Just rerun another test, and the same result.... A picture of the result on copy paper is attached, 100%, 10mm/sec, cant upload .nc file, so have sent a pm. I am afraid Apple are up to their normal tricks, the picture is rotated 90o anticlockwise, the cutting mats are at the Bottom of the emblaser (away from the control panel) really appreciate the support. regards Paul

Hi Many thanks to all who have posted to offer suggestions to get my emblaser 1 in better order. Really appreciate the time to post. Ran the darkly labs calibration file as Giles suggested, looks fine APART from first 1-2" of the path, tried again on plain circles and squares (both drawn in Cut2dlaser and imported as .dxf from inkscape), and they also showed no impression over first 1-2" of path. This is repeatable from any feed speed from 5-20mm/sc. The laser head appears to follow the full path and the laser seems to be firing? Tried to refocus (again) yesterday, dot looks to be getting smaller, right up to the point where the lens fall out!, With the lens just screwed in, seems to be a significant light spill around the laser. Can't recall this from earlier attempts to focus, is this normal. Tried to cut through 2mm mdf, yesterday 15 passes @ 5mm, 100% on 4 watt didn't cut through, couldn't seem anything on the reverse, so clearly not on top form, (that's both me and the emblaser, in case you were wondering) As always, appreciate any help, just hoping the laser head isn't knackered; that may be a very expensive mistake. On another matter, I upgraded to Cut2dLaser 9.0, and new Vtransfer. The upgrade was painless on Windows 10 laptop, don't know what's going on under the bonnet, but only difference I can find in operation is that cutting doesn't start automatically when sent to the machine, need to trigger the cut in Vtransfer when you get the "ToolPath Loaded" info box. For me, that's good, its a hard stop to allow me to check the laser is enabled and the workpiece is where I want it. kind regards Paul

Hi thanks for the responses to my earlier post #1119. I wasn't aware that the beam wasn't round, so I have learnt something. Have continued to play with focus but no improvement in cutting performance on MDF. I have looked at all the connections and can't see any darker marks or burning. I then ran a simple test with a 31mm diameter circle on an old piece of cereal card, 10mm/sec, 1 pass, 4 watt laser. I know the focus isn't where it needs to be, but I was quite surprised by the output - expecting a solid burn line, not cutting in/out as below Seems to me to indicate an intermittent beam? Has anyone got any ideas that can help me fix this thanks in advance Paul

Hi Martin I got a response from Darkly with some suggestions on how to post a pic - I can only echo what others have said about their standards of customer support, I can think of many organisations that could learn a lot from them. Have managed to post same pic as above post on Darkly community and wait for their response. I don't think I am getting an uninterrupted beam, certainly seems oval when very large and clearly out of focus, but difficult to tell when I am getting a far smaller beam, tried looking at in a darkened room and via the "live" photo from an IPad, but still can't be certain. thanks for taking the time to respond. kind regards Paul
