content: Has anyone created a manual or documentation for this machine?My machine came with 15 video's, but these leaves me with lots of question.Some of my questions:Q1) Sales person assured me that the Software works with Windows 10, but video "5.file edition _EN.wmv" has a message indicating only windows 7 is supported. Software version that came with machine is English802B-V2.31. What version of their SW supports windows 10 reliabily?Q2) In windows 10, the app "Camera" can use both camera reliably without issues. Inserted and removed USB plug many times and "Camera" app recognizes camera flawlessly and video works everytime. When I run the V2.31 SW, I need to quit and relaunch the application multiple times before the camera is recognized. Is there a procedure that allows the V2.31 or other version of the SW to launch reliably or do i need to live with this bug?Q3) Load Tab - HeightWhat are the units of measure MM, CM, Mils,What does 0 mean and what does 10 mean?I'm guessing that this is either component heigh or Z1 position of Nozzle. Is this correct?I'm guessing that a wong value with crash the nozzle into the board and damage something. Is this correct?Q4) Load Tab - VisionNone vs Quick vs AccurateWhat Correction is done for each?When should each be used?Q5) Load Tab - PresureI'm guessing this is a puff of air when placing. Is my guess correct?When should this be used?Q6) System Config - Left Stack - FeedWhat does the 4, 8 12, 16 mean?Q7) System Config - Left Stack - PrickCorrectwhat does the default -0.01 -0.01 mean?Q8) System Config - Nozzle - Down to PCBThe default entry is -13.5Using manual control, when i lower Nozzle1 until it touches the PCB, i get a Z1 of -10.15Is the default setting incorrect?Q9) System Config - Nozzle - Down to frontWhat does this mean?Q10) System Config - Nozzle - Pick Delay(ms)what is this and when do i enter something other than 0Q11) System Config - Nozzle - Place Delay(ms)what is this and when do i enter something other than 0Q12) System Config - Camera - Camera 1Should the 0.0351 / 0.0351 Distance / Pixel ever be changed?Angle Offset -0.12, should this be ever changed?What does the delay after Angle offset mean?What does the 75.00 comp threshold mean?Should the Camera Position -41.05, 398.22 0.00 ever be changed?What does the X/Y Offset Threshold of 0.20 mean?What does the Angle Offset Threshold of 0.25 mean?Q13) System Config - Camera - Camera 2Distance / Pixel for this camera is 0.0159 / 0.0159. Should this ever be changed?Nozzle1 offset of 22.75 / 48.70, should these ever be changed?What does Nozzle Threshold: 120.00 mean?Q14) System Config - OtherLeft Prick 1.50 / -37.50, What does this represent and when do i change?X/Y Axix Scale: 0.9968 / 0.9968, what does this represent and when do i change this?User Pressure Sensor - Are chips discarded based on pressure sensor or based on vision failing to see a chip? When do i use this?I will be experimenting, but would rather not break anything. So any answers and insight is appreciated.Regards,John

content: I have TVM802 more than 3 years.I tried to adjust many times and spend many time for this but TVM802 never worked as described or in the youtube video. I think manufacturer also don't have instruction how to adjust machine for real work.In my opinion this machine suitable only for 1206 or largest packages, minimum pitch is 1.27. Otherwise you must adjust placed components manually.

It hasn't arrived here yet, so I can only answer a few questions based off experience using other machines.I uploaded it for anybody who needs it.http://www.siegecraft.us/manuals/TVM802_Manual.pdf

content: Ok, now that I have mine up and running I can answer a few more of these in depth.Vision: Quick vs Accurate.Quick will look at the part once, determine what the offset, and place it while applying that offset.Accurate will look at the part, determine the offset, apply that offset over the camera, and see if it's within tolerance. Then repeat until it is within tolerance.Delay after angle offset:When parts are rotated due to vision correction, it will stop for a moment before performing the next step. Helps work out any jitters.Nozzle Down To Front:I still have no idea what this means exactly. At some position, called "front", it means that's the Z-height the nozzle will travel to. But I haven't a clue where "Front" is.

content: Oh, one more I forgot to add.User Pressure Sensor:There's two values for the pressure sensor (at least in mine), one low and one high.If the vacuum value is below the 'low', it assumes there is no part on the nozzle and immediately tries to re-pick. (potentially dropping a hanging part wherever that decision is made).If the vacuum level is above the 'low', but below the 'high', then it assumes there IS a part on the nozzle re but it's a bad pick. In this case it will drop the part into the discard location then re-pick.If the vacuum level is above the 'high' level, it assumes a good pick and proceeds to vision or placement, depending on your settings.-Hans
